We all can learn from this (be sure to have CC on for subtitles for the video). Via CBS News:
Huug Bosse underwent hip surgery two years ago and now can’t stop cracking up no matter how hard he tries. “It appears that due to the operation, due to the anesthesia, he was laughing more,” Bosse’s wife told the Dutch TV show Man Bijt Hond. “When you are having a discussion and all he does is laughing, then it gets annoying.”
Can this bizarre behavior be explained by a medical condition?
