It's time to play a favorite game of Mr. Man's: guess those buns! As connoisseurs of celebrity ass, we love to think we can guess a celeb's booty from miles away. Let's put this superpower to the test, shall we? Whose heavenly buns are these?

First hint: These buns originally came from Germany.

Second hint: He once filled in for David Letterman when he was supposed to be a guest, but Dave had to call in sick.

Third hint: He's best known for his roles in action-adventure "save the world" movies.

Do you know who it is?

It's Bruce Willis!

Bruce is everyone's favorite action star. The hunky stud with a famous smirk has a range that can do everything from gun-wielding hero to the dark and twisted therapist in The Sixth Sense. We love watching his range when it comes to dudity.
