Bill O'Brien played Peter, the sign-language-cop on the LOCI episode "Silencer"! I now feel like I must go and watch tons of West Wing. He's got four appearances in the first season, that's probably a good place to start. (I'm sorry, but he's hot.)
Random other information: I'm watching LOCI reruns on Bravo, right? And "Con-Text" is on right now, starring Timmy Kirk, and next up? That's right, "Baggage", with Beecher! It's Ozzie night! Hee.
Also, I downloaded a rugby game for the computer. It's got some awesome music, dudes.
