Duchovny is in a treatment program now for his addiction.

Joe Biden thinks the main thing Sarah Palin has on him as a VP candidate is that she's prettier than he is.

"Well, there's obvious differences [between Biden and Palin]," said Biden yesterday. "She's good looking." Of course, he didn't reference anything beyond that –- and we know he likes to throw the compliments around, calling his wife Jill "drop-dead gorgeous" and Barack Obama a "lean, young-looking guy."

File this in the "Who Knew?" category.
