"You can set it to just friends, more than just friends, and ... I can't talk about it." (Tygar talking about an interesting p2p necklace application being played with in Asia.)
"William Shatner was a great actor ... and a good jazz singer too." (Tygar proving even the funniest people sometimes have bad taste. ;)
"It's not twelve o'clock until the last ring." (Tygar on the subject of when class ends).
