A policeman spots an old man driving a rusty pickup truck, its bed overflowing with ducks quacking noisily as they jostle for space. The officer pulls him over and approaches the driver’s window.

“Sir,” the policeman says sternly, “it’s against the rules to have this many ducks downtown. You need to take them to the zoo right away!”

The old man tips his hat and nods sincerely. “You got it, officer. Headed there now,” he says, then drives off.

The next afternoon, while patrolling the same area, the policeman nearly does a double take. The same old man is cruising by in the same truck, still packed with ducks—but this time, every single duck is wearing a tiny Hawaiian shirt and a pair of sunglasses.

The officer turns on his siren and pulls the man over again. “Sir!” he exclaims. “I thought I told you to take these ducks to the zoo!”

The old man smiles and waves a hand. “Oh, I did, officer. We had such a good time that now we’re headed to the beach!”

The policeman sighs as the old man drives away, the ducks quacking happily in their vacation attire.
