re: Most unbelievable story told to you by an adult

Years ago, this guy and his wife were telling stories at dinner. She then tells her husband to tell the funny one about the drive through line at some restaurant. This guy goes into all sorts of detail about his experience at some place in town and its not really that funny and seemed a bit forced, but the wife is laughing away.

A few years later, I was watching a special on the Smothers Brothers, and it turns out that was a routine they did. The dude made a fool of himself copying an old comedy sketch he couldn't really do well.
