Not to pile on, but "courage bladder" really is a cooler superpower than what Green Lantern can do.

Ryan Reynolds is promoting his new movie "Life," but he's also firing more shots at his 2011 movie "Green Lantern." He's been poking fun of himself and that DC Comics movie for years now, with its only saving grace being that it paired Reynolds with his future wife, Blake Lively.

Reynolds was on "The Late Show" last night, taking a spot on the blanket for Stephen Colbert's regular segment, "Big Questions With Even Bigger Stars." While gazing up at the night sky, asking each other tough questions about the universe, they added a joke about Green Lantern:

Ryan Reynolds: "Hey, Stephen, if you could have any superpower, what would it be?"

Stephen Colbert: "Oh, I'd like to have, like, this super-cool alien high-tech ring, and it's green and it has a lantern on it, and I could use my imagination to make anything out of green light."

Long pause, and applause.

Ryan: "Wow. That's a really dumb superpower."

Stephen: "Yeah. What superpower would you want?"

Ryan: "I'd like to be able to pee at a public urinal when someone's standing directly behind me."

Stephen: "Oh. Courage bladder."

Courage bladder! Watch the full segment; the joke about "Avatar" is pretty good, too:

Green Lantern is about to get back in action in the DC Extended Universe. Henry Cavill (Superman) was just posting about the character, who may or may not be played by Armie Hammer in "Green Lantern Corps."

"Life" opens Friday, March 24. For more shenanigans, check out Ryan's insane junket interview with co-star Jake Gyllenhaal.
