Frank had a run in with the cops.

He was the best man at a wedding I went to maybe 10 years ago. Just as funny in real life as he was in the Hangover. His speech about the groom had the whole place dying
I was watching his episode of "comedians in cars getting coffee". He mentions being best man at a wedding and getting up to do the speech.

According to him, he had written a serious speech, but as soon as he got up there, people started laughing and sabotaged the speech.
