Freddie Prinze Jr. is a Super-Nerd ... on 'Psych' (VIDEO)

On last night's episode of 'Psych' (Wednesdays at 10PM ET on USA), Freddie Prinze Jr. played a guy who used to be a nerd obsessed with sci-fi and UFOs and all that but now is a jock with a really hot wife. Only he hasn't really stopped his geeky habits. In fact, he has a secret room in his house where he can indulge in all of his nerddom, including a bunch of computers and collectibles from the original 'Battlestar Galactica' and 'Star Trek: TNG.'

As Prinze explains to the guys, he's a closet nerd...literally.

But to be fair, if you had a woman like that you'd like about your nerdy habits too.
