Married... with Children, Season 10

[Al is trying on shoes for a fat woman named Matilda.]

Matilda:
I don't understand, I was a size six before Aerobic class. All that jumping must've expanded my foot.

Al:
And I see you must've fallen on your butt a time or two.

Matilda:
[Picks up her sneakers] How dare you say that to my face?

Al:
Well I'd say it behind your back, but my car's only got half a tank of gas.
