Conan O'Brien Freaks Out Playing 'Doom' With Super Bowl Stars

"What'd you do? What'd you do? What'd you do?"

You know those "M" ratings mean you need to be mature, right, Conan?

In honor of the upcoming Super Bowl, Conan O'Brien brought in Von Miller from the Denver Broncos, Josh Norman from the Carolina Panthers and even Marshawn Lynch to play the new "Doom" game. And the talk show host just couldn't handle it.

A telltale sign the gore was too much, Conan would give play-by-plays for very obvious things. Quotes include, "Oh! You knocked his head off," and, "What'd you do? What'd you do? What'd you do? You stuck something in his mouth!"

(It's cool, man. I couldn't even make it through 5 minutes of "Doom 3." That stuff is messed up.)

The good news for Conan is this game doesn't come out until May. The bad news is, oh crud, it's coming out in May ... 

"Conan" airs weeknights at 11:00 p.m. ET on TBS.
