The Ike and Tina Tuna is a meal on the Klimpy's menu. Lucille orders the tuna while eating with Lindsay, but when the waitress asks whether she'd like the plate or platter, Lucille is offended. This leads to a brawl between the two, getting the Bluths in the newspaper and hurting George Michael's chances of getting into the Milford School. ("Public Relations")
The meal is named after the musical duo of Ike & Tina Turner.
Lucille: I’ll have the Ike and Tina tuna.
Loretta: Plate or platter?
Lucille: I don’t understand the question, and I won’t respond to it.From "Public Relations"
