Billy Mays appeared on Jay Leno recently to promote his new reality show (Pitchmen, which premiers Wednesday, April 15 at 10 PM EST on Discovery Channel).
Check him out in a skit with President Obama during the opening monologue and the one-on-one interview after Dana Carvey (with jokes thrown in by Carvey, who shares the couch) on NBC's Web site.
Looks like Billy had a lot of fun!
