This is Frank Caliendo on David Letterman. You might recognize him from Frank's picks on the fox pre-game show last season. Sorry if you have dial-up, might take a while to load, but if you wait i guarantee it is worth it. FUNNIEST THING I HAVE EVER SEEN. Really well done, sounds exactly like the guys he is trying to impersonate. I love the sploof on Madden, and he goes on to immitate Bush, Clinton, and Al Pacino.

Another good one is the Jim Rome sploof found here

If you go to his website there are free ringtones, all of them funny as hell
