Charlie Sheen will return to series TV when he appears on the April 12 episode of "Drew Carey’s Improv-A-Ganza" on GSN, according to Deadline.com. It will be "an impromptu appearance."

In actuality, Sheen has already taped the appearance. The show was filmed on Jan. 18 at the MGM Grand in Las Vegas, just prior to Sheen’s Vegas toot with porno stars that landed him in the hospital.
