A very casually dressed Novak Djokovic dropped by Late Show with David Letterman on Tuesday for a wide-ranging interview that covered everything from growing up in war-torn Serbia to his great rivalries with Rafael Nadal and Roger Federer.

This is just the beginning of the heavy pre-U.S. Open media blitz that sees tennis' top players take over New York City. Serena Williams will be a guest of David Letterman's on Thursday.

Hear Djokovic talk about his U.S. Open chances and his crazy flexibility, and watch him threaten to take his shirt off in the clips below:
