This best Goodfellas bit is based on an incident Pesci had with a mobster when he was a waiter. He mentioned it to Scorsese who let him and Liotta improvise the scene. The other actors weren’t told the dialog because Scorsese wanted them to look uncomfortable. Can you believe the two actors just made that up? Genius.
