We often say "You know what they say.....", some years ago I saw a skit about a 20/30 something guy that joins the group called They. These are the ones that come up with all of the "They say.." sayings.
I thought it was very funny look at a different perspective, but for the life of me I can't remember what it was called. I believe I watched it online. It was a 15 minutes or so video. Can't remember much more then that.
