This is a true story that happened recently , playing in the local 8 ball league. The other team was short a player and asked if they could use a fill in guy that had not played in the league before, i didn't care and let them go ahead and let this guy play. So this guy shows up with kind of a chip on his shoulder , so he plays the first game against me . I get the break and come up dry , he takes one shot and scratches , I take ball in hand and run out , he then yells "What the F&%# is this crap putting the ball anywhere on the table!" , I calmly explain the rules to him, he yells "This is Sh%& pool , you don't know how to play pool" , then he says "If you got any balls then lets go to another bar where there is an open table and I will kick your arss all over the place for $100 a game with no ball in hand!" , well to make a long story short , I downright felt terrible afterward about abandoning my team that night, each team had to play with a player short but we still won the match..
So I guess to add to the list , anybody who does not know what ball in hand is.
