I don't usually watch the Simpsons and I'm sure this must be on one of those lists of language gags we see from time to time, but I just saw this gag.

Marge (in the Kwik-E-Mart) Oh, look sugar-free donuts.

Apu - No. That's sugar with free donuts.

(Holds up package and sure enough it says SUGAR, FREE DONUTS)

Funny, Bob.

It's not that different from "Eats, Shoots & Leaves," I suppose.
