Sometimes, you never know who you may run into at a comic book store. Case in point, James Corden had most of the Avengers: Infinity War cast pop up for a tour of Los Angeles. The Star Star Tours, or the star tour that takes the stars on tour.
Corden teaches the crew, most notably Chris Pratt about waiting in lines and buying coffee before the tour makes a stop at a comic book store, much to the shock of everyone inside!
Watch the hilarious clip — and last minute cameo up top.
