Courtesy of my best friend from boarding school...her husband's name is Greg.
Warning: You will most likely be offended if you are a human being.
"One of Greg's coworkers has a mentally disabled 20 year old cousin. One day he called his mom at work and told her he had caught a troll. Statements like this were pretty typical, so she told him that she would check it out when she got home. He called again a few hours later still excited about the troll he had caught, and she again said he could show her when she came home. So, she came home and immediately he told her he had the troll in his closet. He took her to his room and there was a chair jammed under the closet handle. He opened up the closet and he had a midget Jehovah's witness in there. I could not stop laughing when Greg told me this. I think this is the funniest true story I have ever heard."
I know I can't laugh at this, but I can't stop.
