And Han Solo was not played by Christopher Walken

Watching end credits of Return of the Jedi:

Girl: Where's Scott Baio?
Guy: What?
Girl: Scott Baio, I don't see his name in the credits.
Guy: Scott Baio was not in Star Wars!
Girl: Yes, he was! He was celebrating at the end! The pilot!
Guy: Scott Baio is not Wedge Antilles!
