Ok, here are two that come to mind:
1) "THE BEST HIT AND RUN OF ALL TIME"
On a busy Saturday evening we had a list 30 players deep for 1/2 NL. We were short dealers and it was a rare occasion that players had to wait 1-2 hours for a seat. We finally opened a new game and two women sat side by side with $20 each in white. I informed the new players that the minimum was $40 and the one lady slid her chips to the other (and proceeded to just sit there with no money and not say a word.) I asked here politely if she wanted to buy some chips and she said "No." I then told here that if she wanted to watch her friend play she would have to get out of the chair because other people were waiting for a seat. She promptly stood up and stood behind her friend. I dealt for the button and the remaining women started UTG. I deal out the cards and she is staring into my eyes. I say, "Two to call" and the lady responds, "Can I go allin?" I reply, "Sure!" The lady pushes her two stacks of white chips forward and everyone snap folds, she wins $3. As I am shuffling for the next hand I say, "Ok small and big blinds." The lady looks at me again and says, "Can I leave now?" I say, "Yes" and the two women leave, never to be seen again. These women waited about 90 minutes to play one hand and win $3, or $1.50 each if they split their profits.
2) "THE WORST C-BET OF ALL TIME"
On an average (passive) 1-2NL table the BB had an average stack of exactly $76. 5-6 people limp and the BB ($76) raised to $25 (first raise over $6 I saw at the table all night.) One player from MP called and it's heads up to a flop of J 5 6 two hearts. BB leads $50 and the other player notices that BB has only $1 left and says, "Allin." The BB tanks, says something very cliche like, "Well I guess you got it!" and decides to fold and save his $1.
