Quote from Martin in Come Lie with Me
Frasier: Oh, Dad. This is a small thing but you left the sponge in the sink again. Martin: So? Frasier: Well, as I mentioned last evening, if it stays wet, not only does it begin to smell but it becomes a breeding ground for bacteria. Martin: So? Frasier: So, if I were to, say, wipe up that salsa that you spilled on the table just now, I would be leaving behind bacteria such as salmonella, listeria, flagella. Now wouldn't that bother you? Martin: Yeah, I guess you're right. It would bother me. I wouldn't dream of touching that sponge now. [Martin whistles. Eddie comes and licks the table clean.] Frasier: Ah, yes. Our own foul-breathed, little handy-wipe.
