Mission Accomplished: Will Ferrell Makes 'Em Laugh So Hard They Cry (and Pee?)

Several stars come out as the comedian receives the Mark Twain Prize for American Humor in Washington, D.C.

There may not have been any Frank the Tank-style streaking going on last night, but there was certainly plenty of laughs.

That's because several funny folks came out on Sunday to honor Will Ferrell, who was presented with the 14th Annual Mark Twain Prize for American Humor in Washington, D.C. (A fitting place to be celebrated, obviously, considering his popular impression of President George W. Bush.)

So, who all was there, and what did they say and do to celebrate the man who makes us smile?

Jack Black helped get the evening started off on a high note. Literally. The comic actor took the stage and belted out a reworked version of the Queen classic "We Will Rock You" utilizing such lyrics as "Will, Will, Will, will rock you!"

"It's about time he got some official Washington, D.C., props," said Black. "He's crazy funny. He makes you laugh so hard you cry and pee simultaneously."

Proof of that was made as several clips were shown of some of Ferrell's movies including Old School, Talladega Nights: The Ballad of Ricky Bobby and Anchorman: The Legend of Ron Burgundy as well as highlights from his years on Saturday Night Live.

Fellow SNL alum Molly Shannon quipped that Ferrell's "agents and manager clearly bought this for him" with regard to the award that has been received previously by the likes of Tina Fey, Bill Cosby, George Carlin, Steve Martin and Richard Pryor.

Conan O'Brien was also on hand to return a favor of sorts to his pal. After all, it was Ferrell who appeared as O'Brien's first, as well as last, guest during his short-lived stint as host of the Tonight Show.

"It's a rare friend who's going to stick with you for five and a half months," remarked O'Brien.

Also on the guest list were Ben Stiller, Paul Rudd, Andy Samberg, Ed Asner, Tim Meadows and John C. Reilly.

Ferrell eventually accepted the bronze bust of Mark Twain ("It's about time," he cracked)—and then, in true Ferrell fashion, he dropped it, causing it to shatter into pieces.

Of course, it was a fake. But it still gave the guy a chance to do exactly what he was being honored for in the first place.

"If my children try to touch this, I will beat them," he joked while scrambling to put it back together.

Will Ferrell: The Kennedy Center Mark Twain Prize will air Oct. 31 on PBS.
