Conan O'Brien's beard comes under threat from Will Ferrell

conan-will-ferrell-beard.jpg Conan O'Brien turned 48 on Monday (April 18), and his beard turned 1 a couple months ago.

We're guessing Conan has a lot of years left in him. His beard? Well, if a certain movie star has his way, it may not be long for this world.

Will Ferrell sent in a video to the "Conan" Fan Correction Challenge on Monday, and in it he claims to have found a mistake on the show: "The error that I found is your beard," he says. "That thing's a huge mistake, and I'm gonna come there and fix it myself."

D-Day for the beard, Ferrell says, is Monday, May 2, when he's scheduled to be a guest on "Conan." "Circle the date on your calendar," he warns O'Brien, "because I am circling your face like a like a vulture ... who eats hair."

The slightly NSFW challenge from Ferrell is below. What do you think? Is it time for the beard to go, or should Conan resist Ferrell's threat?
