Weirdal_conan “Weird Al” Yankovic has had much success in his decades as a satirical recording artist, but not quite like he has had this week.

Yankovic’s most recent album, Alpocalypse, debuted at #9 on the Billboard charts (a rare feat for any comedic act) — and Conan O’Brien finally allowed him to perform on his TV show, doing so by also granting him the privilege of writing and singing lyrics for Conan.

Of course, the joke’s on Conan.

Roll the clip!
