Last night.
Me, while leafing through The Secret Order of the Gumm Street Girls, prior to beginning it: Oh, this is Wizard of Oz related. Gumm Street Girls must be a Judy Garland reference.
Josh: Oh? Why's that?
Me: Because Frances Gumm was Judy Garland's real name.
Josh: AUUUGH. Why do you KNOW things like that? It's like living with frickin' Alec Trebek.
Me: <pause while I struggle valiantly to keep my mouth shut>
Yeah, actually, I'm pretty sure it's AleX Trebec.
Josh: AUUUGH.
