Now Here in Spamalot

Clay Aiken, who recently confessed to thinking that Monty Python was a person, has nevertheless joined the cast of the Tony Award-winning musical Monty Python's Spamalot. The American Idol runner-up takes on the roles originally played by David Hyde Pierce, including Sir Robin, the Not-Quite-So-Brave-as-Sir Lancelot.

Also joining -- actually, returning to -- the cast is Christopher Sieber, the original (and Tony-nominated) Sir Galahad. Considering that he will be in the upcoming Shrek the Musical, it's safe to assume he likes medieval times.
