Is there nothing Charlie Sheen can't do? Other than keep a job, date one woman at a time and not sound like a mad libs game come to life? Yes. Improvise.
That said, this clip of Sheen joining the stage with the seasoned improvisers on Drew Carey's "Improv-a-Ganza," the newest reboot of the "Whose Line Is It Anyway" format, is hilarious anyway. Watching the team — Carey, Ryan Stiles, Greg Proops, Colin Mochrie, Chip Esten and Jeff Davis — work around Sheen's "contributions" to the story they were inventing on the spot, is hysterically awkward. The line of the night definitely goes to Greg Proops for his follow-up to Sheen's second reference to a necrophilic encounter.
Note: The clip is bleeped, so it's only slightly not safe for work.
