3 generations of males went to an old-fashioned store...

The young man asked for a pound of raisins from the pretty lady behind the counter. She had to climb a ladder to fill the order, revealing her naked flesh under her short skirt. Then, she asked his dad what he wanted.

Wanting to see a panty-less beauty climb the stairs again, he too asked for a pound of raisins. This time she caught on while grabbing the raisins, looking down on the men getting their carnal delights.

She then asked the grandpa, "I suppose yours is raisin' too?" "No," the old fella said, "but it is twitchin' a bit."
