Not really the funniest thing I've heard at a table, but certainly one of the most odd tirades I've been involved in.
Just sat down at this 2/5 NLHE table about 45 minutes before this hand. A older short stack at the table (I thought he had about $100-110 in front of him) raises to $30 in middle position. Everyone fold to me in the BB. I look down at KK and raise it $80 on top, with the intention of putting him all-in. Turns out he must have started the hand with $115, because after he calls the extra $80 he still had $5 left. Flop comes out K-7-3 rainbow. I throw one $5 chip in the pot to put him all-in. I wasn't trying to be a smart-ass by betting $5 and putting him all-in. In fact, I did it in part because I thought it would be more dickish to "slowplay" top set under the circumstances. Anyway, long story short, he mumbles something under his breath, throws his last $5 chip into the pot. Turn is a Q, river is a 9. I turn over my KK. He then flips over and slams his JT on the table, pumps his fist and loudly declares that justice has been served. He then proceeds to get in my face telling me that I got what I deserved and that I have no class. He goes one and tells me that this is a gentlemen's game, and that you don't go after a man's last $5 like that. He then goes back to calling me classless. I've seen people react in many different ways to getting lucky and hitting runner-runner when they were drawing almost dead, but this was a first.
The table is a bit stunned. I'm a bit stunned. He then gets up to go outside and smoke, and it was at that point that the rest of the table turned to me and asked WTF that was all about. I told them I had no idea, never seen the dude before in my entire life. Very, very strange (and in hindsight, a little funny too I suppose).
