Put the Seinfeld Season 1 DVD in your player and go to the episode called "The Stock Tip". Skip ahead to chapter 3 (the last scene of the episode) where the group is at the restaurant. Watch George pay for their meal, look at the receipt, then take back a bill. Pause just as George takes the money back and frame-by-frame forward. It appears the George is cheap, having paid in only $1 bills.
