If you didn’t know, Paul has pulled the same prank on Conan since 2004: he sets up the clip for his latest project very seriously, and instead of the project he’s promoting, it’s a clip from the 1998 box office flop and E.T. knock-off Mac & Me.

He first played the prank while promoting the series finale of Friends — and he hasn’t stopped ever since!
