Will Ferrell stopped by The Late Show with David Letterman last night and was a memorable talk show guest as always. Ferrell said that he has been "bitten by the Broadway bug" during his run of You're Welcome, America... and doesn't plan to stop there. Up next for the comedian is the new production of West Side Story (where he'll play "Gary") and he gave the Late Show audience a little preview of the performance.

The actual new West Side Story is currently in previews the Palace Theater (performers were actually on the Late Show on Thursday). This version is being directed by Arthur Laurents, who wrote the original book. As for Ferrell's current endeavor, his one-man run as former President George W. Bush (with some dancing assistance from his brother), it will close this weekend—but not before a live telecast (penis picture and all) of it airs tonight on HBO.
