Come on, vent, tell your stories. We've all seen people do unbelievable things at meaningless league matches, and these stories are always funny (infuriating) to read, so spill the beans on your worst/funniest 'douchebag league player moment'! 
Tournament stories are fine too.
To contribute I have two:
1. The Sands Of Time team.
Years ago I was playing in a small travel-bar-box league. The first night I played I was talking with the opposing team and one of them says "Oh, you're new? Wait till you guys get to play the hourglass team!" They all laughed and refused to explain to us what this meant. Fast forward a couple weeks. We're visiting a team playing out of an actual pool hall (not just a bar) that had two little bar boxes in a sea of 9 foots. It was a Sunday night, and the place was dead. Two guys sitting having a beer, a couple guys in the very back playing snooker, and otherwise completely empty except us and the opposing team. No jukebox, no tv noise, nothing but silence. So we introduce ourselves, do the paperwork, and the first match gets started. Their guy breaks, makes a ball, runs a couple, then misses. Our guy approaches the table, grabs the chalk, and BANG there is this huge crash from next to us. So loud we all jumped, and one of our guys actually spilled his beer he was taking a sip of. So we're looking around like "Wtf is going on?!" and the team captain at the round table next to us points to the middle of his table where a little tiny wooden hourglass is sitting. Then he loudly says "Rules state you have a 1 minute shot clock starting when you approach the table, and we time every shot." We're all sitting there dumbfounded, our guy shoots, misses. Their guy approaches table, we all look over. Hourglass is not turned over. Dead quiet. He makes a shot or two, misses. Our guy approaches the table and reaches for the chalk. BANG, their team captain has upended the hourglass and slammed it hard on the table. One of us says "Why are you slamming it down so f*cking hard?" and their captain smiles and says "sorry I didn't notice...didn't sound so hard to me." We grumble, but being new, figured they couldn't be jerks the entire time so we don't throw a fit. Oh how wrong we were. The match continues with this BS the rest of the way: every time their guy shot, no hourglass, no noise, dead silence. Every time one of us go to shoot, BANG hourglass smacked on table. So match ends, we leave. Team captain calls LO to complain. LO says basically that unless the sound is coming as the player gets down to shoot there is nothing technically illegal about it.
This team was notorious for doing this, and since nothing was being done about it we found ways to torment them back after playing them a few times. Most of the time we all took turns wearing headphones and a discman while shooting, but one time a guy on our team wore tuxedo shoes, the kind that squeak really loudly on hard floors, and he would get up to walk to the bar or bathroom while their guys were shooting. Once we loaded up the jukebox with $20 (back when you got 3 plays for a dollar) and played the "happy birthday" song over and over again (had to bribe the bartender not to unplug it on that one). Another time our team captain brought a big bag of bubblelicious chewing gum and we all started blowing bubbles and chewing loudly while they were shooting. We ended up leaving that league after a couple sessions, and I heard later that the hourglass team finally got told to knock it off.
2. Joe Dirt loses count.
Was playing a guy in a league match a couple years ago. His nickname was Joe Dirt because he not only looked like Joe Dirt, he smelled, wore wife beaters, had a mullet, and even sounded like him. So anyways, Joe Dirt and I are playing 9 ball. While I am at the table, he's sitting about 5 feet away trying to impress his teammates with how badly he is going to kick my ass. I'm half deaf and don't really mind until it gets to a loud "This guy f*cking sucks, and when he misses I am going to kick the sh*t out of him". While I'm down on a shot. In mid stroke. I tell him to stfu while people are shooting and we get in an argument about it. His main defense is "I can say whatever I want when I am over sitting with my friends." So I call him a worthless tool and the match continues.
I need to win 4 games and after I have already won 2, I make a shot and get shape on the 9. As I bend over to shoot in the 9 about a foot into a pocket, he storms over and grabs the 9 and slams it in the pocket. I still need to win 1 more game but Joe Dirt says loudly "That's bullsh*t luck, I can't believe you won that match, its f-ing bs." So I say loudly "Wait, you're conceding?" and he replies "Yeah, I already yanked the 9 ball off the table." I repeat myself "You're conceding the match?" and he says "yeah, I concede the match. You're a lucky asshole". There were about 15 witnesses to this, besides our two teams. He then breaks his cue down and storms off. Well someone on his team chases him down, and he comes running back and starts racking the balls, turns to me and says "you're an asshole for not telling me you needed one more, and I'm going to make you pay for it now." I tell him he has already conceded the match twice, broken down his cue, and left the area. The match is over, and he can go f*ck himself. He flips out. I tell him if he wasn't such a lowlife piece of sh*t I would have never allowed him to forfeit, but what goes around comes around. He calls the league operator at home (!) and is talking to him on the phone for a few minutes.
Our league operator "Mr Clean" not only operated the league, he owned a pool store that sold cues and such. Well Joe Dirt had saved up his food stamps and bought a Viking cue (and got ripped off badly on the price to boot) by Mr Clean, who was his good bestest buddy. So they hand me the phone, and Mr Clean tells me I must finish the match, or he will call me for forfeiting due to "bad sportsmanship"! I tell Mr Clean that I'm holding a current nationwide league 9 ball rules handbook, which clearly states "An opponent breaking down his stick and leaving the table, or verbally stating a concession at any time means the match is over and the other player has won the match." Mr Clean replies that my opponent did not know the current score on games, and how many I needed to win. I reply (with the page number) that the rule book states it is not up to your opponent to keep score for you, each team will keep score themselves and keep their own player informed at all times. Mr Clean is adamant, finish the match or I lose.
The good part of this entire thing was that I did end up winning the match (on a really ugly called-cheese shot on the 9, hah!), the sad part was me emailing the relevant parts of the rules he ignored to the LO and him dismissing the entire thing as "well he's a nice guy, and you were being mean for trying to let him concede like that"! :lol:
So anyways, I know everyone has seen "that guy" pull some douchebag/idiotic stuff at league or tournaments, so fire away and tell us about them!
