Most embarrasing or retarded thing you ever did at a casino

wow....mine is starting not to seem so bad...

Monte Carlo NL....I had been up playing poker for 2 days and it was now 3:30am. I was crushing the table, and since I was the only female at the table was getting all kinds of crap from angry players who kept repeatedly buying in to try and beat me. I look down at my cards and at the flop and wow! I have another straight....I put my opponent all in (the pot ended up being $500+ ($200 was mine). The dealer said, 'Showdown, please'.
I SLAM my cards down on the table, stand up and say Ha! I have a straight! The dealer begins to push the pot to me when all of a sudden both he and several other players say... where? I only had a 4 card straight. Doh!

Didn't turn out too bad - I just played the dumb broad part (which sure wasn't too hard since that WAS pretty fking dumb) and got most of it back, eventually. I sure did feel like a total retard, though.... especially since they were all waiting for me to take a loss.
