Worst ever:
It was near the end of regular season, about 8 years ago, or so. We had to play the patriots twice in about 3 weeks. We lost the first of the 2.
I was watching the 2nd one at a friend's house. Another friend was there that was a really obnoxious Cowboys fan (this is when the Cowboys were still good). He was always saying "Marino sucks...he's an old has-been" just to get under my skin. He kept wanting to bet on the game, and I don't usually do that, but I finally gave in b/c he was talking so much trash.
Added on to the $20 bet or whatever it was, we had this deal as part of the bet:
If phins win, he signs a note to me stating that he knows Marino is the Greatest QB of all time.
If phins lose, I sign a note to him stating that Marino is the biggest loser or whatever.
Well, the phins lost. This was the game where the Pat's LB's seemed to know the audibles or something, b/c marino audibled to a slant, and the LB did the signal to his guys and then ran over and got the INT for a TD.
I gave him the $20, wrote the note, and walked out the door without saying a word. I was mad about that forever. I still kinda am, b/c he probably still has that note somewhere.
