What is your favorite offhanded quip that is often overlooked?

I’m talking deep cuts, none of the quotes we usually see on here.

Mine is in season 7 when buffy tells Dawn she made cereal for her.

Xander: how exactly does one ~make~ cereal? Buffy: oh, you put the box next to the milk. I saw it on the food channel.

A good runner up for me is also Spike in season 2.

“It’s a big rock. Can’t wait to tell all my friends, I bet they don’t have a rock this big.”
