On Wednesday, the actor "surprised" Kimmel by showing up at his office, assuming he'd be appearing on the show later that day. After finding out he made a mistake, Pratt insisted on a quick interview anyway, saying, "Let's just bang one out."
Kimmel admits sometimes celebrities who have been scheduled for the show haven't shown up, but this is the first time the opposite has happened. It's a good thing Pratt's "great anecdotes" made it all worth it.
"Jimmy Kimmel Live" airs weeknights at 11:35 p.m. ET on ABC.
