What do crows use when they get a phone?
A "CAWing" card!
Listen up, buttercup. This joke is for birdbrains like you, get it? It's saying that crows would use a "CAWing" card, because crows "caw." "Caw" is the sound crows make. You knew that right? Maybe you should stick to counting your fingers and toes, and leave the thinkin' to the bears.
