Late Night Pick: Tenacious D, Will Ferrell

Looks like a comedy fest on Conan tonight. Jack Black and Kyle Gass, collectively known as Tenacious D, will perform. Hopefully, no one will get stabbed. Also, on the show is Will Ferrell, who has been known to engage in a knife fight. Conan is on TBS at 11 PM and then repeated at 1 AM.
