I was watching a friend (whose skills with the cue I respect immensely) get ready to break a rack of 9-ball in a local tournament. All the tables around his tables had matches going on, in progress. My friend is known for his powerful break. The particular venue he's playing at requires "break cloths" but he doesn't know it at the time (he was practicing, getting ready for his first match). He sets the cue ball on the head spot, which is not his normal preferred spot, but thinks "ah what the heck -- I'm just going to whack 'em from here." What he doesn't know is that the head spot has a deep divot -- he doesn't notice when he set the cue ball down on it, it immediately rolled into the divot and was ever so slightly rocking back and forth settling into the divot. (He's too busy putting his cue together.)
He winds up and whacks that cue ball Bustamante-style. Since the cue ball is in a divot, it immediately takes to the air, and launches over the rack, over the table next to his, AND LANDS TWO TABLES AWAY, RIGHT OVER THE BACK OF THE PLAYER BENT DOWN ON A SHOT (he's facing away from my friend's table), HITTING THAT PLAYER'S CUE BALL JUST AS HE PULLED HIS STICK BACK TO STROKE THE SHOT, AND MADE THE 2-9 COMBINATION THAT PARTICULAR PLAYER WAS SHOOTING AT!!! (Can you believe it?!?)
The whole place just fell out laughing -- including me. I'd never seen anything like it. My friend was quite embarrassed, and he was dumbfounded for a moment trying to figure out why the cue ball launched like that, even though he hit it dead in the face with a level cue.
For me, the most embarrassing moment was learning the hard way why it's important to break with a completely level cue (not angled downward at time of impact). I broke -- hard -- and the cue ball went slightly airborne, not touching the table at all, hitting the head ball dead in the face. The result was the cue ball rocketed straight up in the air -- taking out the fluorescent light (this place had no covers on the light fixtures -- just exposed fluorescent tube bulbs). BOOM!!! The fluorescent tubes imploded as expected, and a shower of broken glass, the pronged socket ends of the bulbs, and the poisionous white powder rained upon the table, with the light fixture swaying gently to and fro. Needless to say, the owner was miffed enough to throw me out, and he evacuated everyone within a table's distance all the way around my table, so that they wouldn't breathe in the white powder. (He knew me well, but at the same time he needed to make an example out of me by throwing me out, because he certainly didn't want to give the impression that this type of event was "funny" or entertaining and have folks actually trying to aim for the lights on the break.)
Anyway, there's two for me. Hope they're entertaining!
