Bob Saget -- dirtiest man in America:

“Saget is the dirtiest motherfucking cocksucker that ever walked the face of the earth!” said [Penn] Jillette. “Doing those little bullshit family shows, playing the retarded fucking squeaky dickless dad—that’s not Saget! That’s a joke. You go to a restaurant with Saget and before he orders food, he’ll be talking to the waitress about fucking his daughters in the ass.”
