Dallas Mavericks' star Dirk Nowitzki made a guest appearance on 'Conan' on Monday night. He was on the show to administer the Texas Citizenship Test to visiting host Conan O'Brien.

The 'Conan' show is visiting Dallas all week and this bit involved several jokes making fun of other Texas sports teams (other than the Mavs). The San Antonio Spurs, Dallas Cowboys, Texas Rangers, Houston Rockets all got plenty of mention in the six minute bit.

Well done by Dirk who is never one to shy away from doing comedy bits...good or bad.
