DAVE: [on machine] Hey, my name’s Dave Rygalski, I’m calling about the ad. I left my number before, so call when you get a chance.
This is our introduction to Dave Rygalski, who later becomes Lane’s band mate, and eventually her boyfriend. We first hear him on Lorelai’s answering machine, and we know he’s keen, because this is the second time that he’s phoned.
There is a mysterious female voice in the background, leaving it open whether Dave has a girlfriend, a sister, or a female friend.
