What made you giggle today?

Someone posted a joke I’d actually never heard before on Facebook:

A blonde, a brunette, and a redhead are running from the police. They find three potato sacks in an alley and hide in them. The police stop at the alley and see the three potato sacks. They kick the sack with the brunette in it, and she squeaks like a rat. They kick the sack with the redhead in it, and she meows like a cat. Then they kick the third sack, and the blonde yells, “POTATOES!”
