One episode of All in the Family had Edith finding out the meal she cooked contained horsemeat.
Archie: I gotta admit (unaware), you cooked up a real winner tonight.
Mike (who knows): Pretty close, Arch (bangs his hands down on his thighs to simulate hoofbeats)
Archie: Look at that, he doesn’t even use a napkin, the slob!
(Edith runs into kitchen, distraught)
Edith: I can’t help it. It’s from a horse...I mean,
the Queen RIDES a horse
Gloria: Ma, they say it tastes just like chicken
Edith: But the Queen don’t RIDE a chicken!
