The guy and his blonde date were sitting on a park bench, enjoying the nice summer afternoon.
Suddenly, the fellow feels something wet plop on his head. He reaches up and sure enough, there’s a pile of pigeon poop in his hair. He looks up, his date sees him excited and looking, so she looks upwards too. There’s a pigeon circling above, and then the pigeon flies away, down the walkway and through the trees.
The fellow says, “Do you have some tissue or toilet paper?”
His date says, “What for? That bird has to be at least two blocks away by now. You’re never going to catch it.”
