This thread reminds me of...
(sorry U.K. folks and anyone too young to remember)
The TV series A.L.F., when Lynn sneaks a Thanksgiving dinner plate up to the Alien Life Form:

ALF: (poking wobbly orange mass on plate) What is that? Rubber dog vomit?
LYNN: (insulted) It's pumpkin jello.
ALF: I can't eat that! Hey -- I never heard myself say *that* before."

I have unfortunately had many opportunities to use this quote. Mrs Highlandman is rarely amused.
