Basically just Mythbusters if counting those airing right now.

In the past -- ohh, Futurama, Buffy, X-Files, The 4400, Battlestar Galactica to give some sci-fi ones.

I also use to watch Conan quite regularly.
And sometimes that "Dirty Jobs" show on Discovery Channel. I enjoy his personality and dry humor, hehe.
Haha, I loved Alan Partridge too btw... They even aired it for a while here in Sweden.

Damn, he needs more international recognition, he's sure worth it!
Little Britain was also awesome while it aired here...
"The computer says no." Hehe, the funniest thing is that that's basically what you experience in real life.
