LANE: That is not Dave Rygalski … I mean, not the one that I’m in a band with. That is Dave Rygalski, local Christian guitar player that my mom and I met very briefly and innocently at the dance marathon, and that I coincidentally ran across again when I found his ad seeking Christian guitar accompaniment gigs up on our church bulletin board.
Lorelai and Rory notice that Dave is playing guitar at the Kim’s Thanksgiving dinner. Lane quickly explains that she has set up another zany scheme, whereby Dave came all the way to Stars Hollow at five in the morning in order to have a five minute conversation with Mrs Kim and eat faux egg sandwiches. Lane then put a fake ad up for Dave on their church bulletin board, and pretended to find it in front of her mother.
This is the kind of thing Henry couldn’t put up with (and who could blame him?), but Dave willingly goes along with it, in the faint hope that Mrs Kim might let them date some day. He obviously really likes Lane.
