What if Britney Spears were president? David Letterman's Top 10 answers  

would the United States be like if Britney Spears were the president?

Here are some observations from David Letterman's Top 10 segment Tuesday night, presented by Britney herself. In a bikini.

"I'd be the first president to wear eyeshadow since Nixon," she says.

No. 9? "We would only invade fun places like Cabo."

And as No. 8, "Free pie for everybody."

But wait, there was more -- oh, never mind.

Funny or lame? Is it just us or has Dave lost his edge?
