It looks like Fred Durst has snapped out of the funk of that insane juice cleanse debacle. The Limp Bizkit frontman seemed a sight more encouraged last night as he busted out some pretty ballsy karaoke at a pub on Sunset Boulevard in L.A., along with fellow manchild Nick Swardson and Reno 911 star Cedric Yarborough. The night included a cover of his own song, "Nookie." Don’t worry, though — just in case we were worried about his mental state, according to TMZ, who captured the “performance” on tape, he also whipped out a cover of Gnarls Barkley’s "Crazy." And Durst sort of remembered the words to his 1999 hit (he only looked at the screen… well, the entire time). Does this count as a preview for Douchebag? To think, 3,000 miles away, Jay-Z was rapping his own songs onstage at Carnegie Hall.
