Penn & Teller on Psychic Detectives.

[Skep]

Teller had a nice monologue in Penn and Teller get Killed.

And he's been interviewed on Fresh Air, I think.

He also does a lot of voiceover work, the film Lightyears comes to mind, and the two of them actually sing really well too. A friend of mine saw them sing years ago.
