I can't remember who threatened suits before, but he was all the time making off the cuff remarks about products, other shows, places of business, etc. He was constantly getting in trouble.
There was an old woman who was caught on videotape at a ballpark eating a peach in a sloppy manner.
(go ahead, diagram that sentence, I dare ya!)
Dave showed the tape over and over and the woman either sued, or threatened to sue.
