Frasier: I had a piece of toast!
Martin: Yeah, and you didn't use a plate like I asked you too, and you put it in under the counter. And all because you left a bunch a crumbs and toast sweat there!
Niles: Toast sweat?
Frasier: Yes, yes, it's when you put a piece of hot toast on any surface, and it leaves droplets of dew behind. Haven't you heard dad's lecture on the evils of toast sweat? It's the scourge of our times.
"Flip my toast over before it sweats all over my plate."
