This one my daughter told me:

Two robins are in a field, stuffing their faces with all the worms they can find. Some time later they both finish eating but to their dismay discover that they've eaten too much and are too heavy to fly up into the nest. So they decide to just relax in the sun until they can fly again.

Meanwhile, a cat happens to stroll by. He sees these two robins just sitting there and without a moments hesitation, pounces on them and gobbles them up. The cat then licks his chops and says, "You know, I've always loved Baskin Robins."
