This was a huge wedding with about 300 guests. After the wedding at the reception, the groom got up on stage at the microphone to talk to the crowd. He said that he wanted to thank everyone for coming, many from long distances, to support them at their wedding. He especially wanted to thank the bride's and groom's families for coming.

To thank everyone for coming and bringing gifts and everything, he said he wanted to give everyone a gift from him. So taped to the bottom of everyone's chair was a manila envelope. He said that was his gift to everyone, and told them to open it.

Inside the manilla envelope was an 8x10 picture of his best man having sex with the bride. (He must have gotten suspicious of the two of them and hired a private detective to trail them.) After he stood there and watched people's reactions for a couple of minutes, he turned to the best man and said Fuck You, he turned to the bride and said Fuck You, and then said I'm out of here.

He got the marriage annulled the next day.

While most of us would have broken it off immediately after we found out about the affair, this guy goes through with in anyway. His revenge: making the bride's parents pay for a 300 guest wedding and reception, letting everyone know exactly what did happen, and trashing the bride's and best man's reputations in front of friends, family, grandparents, etc.
