Obama, continuing the cross country media blitz, stopped by the David Letterman show tonight. Showing that as a Leo, he still has a sense of humor.

David Letterman, announced the top ten reasons, why Obama appeared on his show:

• 10. Heard the lady with the heart-shaped potato was gonna be here.
• 9. Thought it would be fun to watch someone else get heckled.
• 8. Something to do with that whole Cash For Clunkers deal.
• 7. Every president since Teddy Roosevelt has done it.
• 6. Someone offers you 600 bucks, you take it ladies and gentlemen.
• 5. We told him Megan Fox would be here.
• 4. Needed some time to hang out before check-in time at his hotel.
• 3. I have no idea.
• 2. Said yes, without thinking, like Bush did with Iraq.
• 1. Wanted to congratulate Dave on the big Emmy win.

I love David Letterman, very funny guy. Watch the video!
