Should Charlie Sheen make a "Glee" appearance? "Glee" loves artists-in-the-news, and Sheen would be perfect as the 'angry guy posing as an 18-year-old.'

Charlie can also sing, as noted in some of his webcast outtakes.

He would be the perfect (new) "Glee" bad boy, a ragged-looking meta teen who can still wear a football jersey, kinda.

Of course, Sheen would be killed before the end of the show -- or, they could make him a recurring character, as the writers would benefit from Sheen's daily story arcs.

Hopefully, Sheen would be asked to come back and get involved in some nasty confrontations (on the show).

Sheen-mania meets Glee-mania!   Winning!  "GLEEN!" 

Here's a quick summary of one episode, riffing on his last name:

Sheen the so-called Teen/that's not Caffeine/what's in the Canteen?

Going to be a Marine?/better check your Hygiene/you fucked someone Sixteen??
