True Love (I) (1989)
Michael: [posing for a photo] Everyone say, "Wedding nightmare"!
Maître d': We often color the potatoes to match the colors of the wedding.
Donna: Oh, yeah?
Maître d': But with rainbow, you can go with anything. Might I suggest a pale blue?
Michael: Wait a minute, wait a minute - did you say blue mashed potatoes?
Maître d': Yes.
Michael: No, we're not having blue mashed potatoes at this wedding.
Donna: What kind of blue?
Maître d': Sort of a sky blue.
Michael: Get out of here! I'm not eating blue food.
