Evil Dave Letterman Can't Read -- And It's Hilarious

The voice-alike artist appropriately also named Dave stammers his way through another side-splitting appearance

Evil Dave Letterman called in to discuss his upcoming appearance on 'Jimmy Kimmel Live' ("I can't help but feel like Jimmy might be queer for me.") and mangled nearly every punchline the staff had written for him.

Dave said he'd like to meet Jimmy's ex, Sarah Silverman: "I saw her nude in a movie, and I'd like to gnaw on her beaver like a dog with a rawhide chew." But he blew it, pronouncing gnaw like "gone."
