Chris Evans Scares the Crap Out of Scarlett Johansson

The Avengers are a bunch of known pranksters, buddies who mess with each other constantly, and one of the biggest perpetrators is Chris Evans. So when his pal and co-star Scarlett Johansson was on Ellen chatting about how much they've worked together and how well they know each other, he couldn't resist popping up and scaring the sh-t out of her.

Good to see they're still tight after the stupid Black Widow comments he and Jeremy Renner made (Evans's infinitely superior apology probably helped). The two then played a round of "Avenger? I Hardly Know Her," answering trivia questions about each other. Spoiler: All the Chris questions involve photos of him in various stages of undress. Johansson can't help but say, "Look at you! You're a beast!" and we gleefully agree.
