Josh Brolin stopped by The Tonight Show on Tuesday and boy, did he bring the laughs. The Deadpool 2 actor, who stars as Thanos in this year's biggest film, Avengers: Infinity War, chatted with host Jimmy Fallon about how he manages to keep a level head with all of recent his success. But before that, Brolin took a moment to flaunt his best assets showing off his backside to the audience, and all we can think about is those fans who can't stop talking about how Thanos is a "thicc daddy". Yes, really. Watch the video above to see Brolin try different voices for Thanos and prepare to laugh your butt off, pun intended.
