Late one Sunday afternoon, a blonde from a small town was taking a long walk through a nearby meadow when she was surprised to see a parachutist trapped in the high branches of a tree.
"Help!" he cried when he spotted her down below.
"What are you doing up there?" she called back.
"I was skydiving," he answered, "and my parachute didn't open!" The blonde rolled her eyes.
"Well, of course it didn't.If you'd just asked one of the locals, anybody could've told you that *nothing* around here opens on a Sunday!"
