"Raisin Bread" joke

A general store owner hires a young female clerk who likes to wear very short skirts and thong panties.

One day a young man enters the store, glances at the clerk and glances at the loaves of bread behind the counter. Noticing the length of her skirt (or general lack thereof) and the location of the raisin bread, he has a brilliant idea.

"I'd like some raisin bread please", the man says politely. The female clerk nods and climbs up a ladder to reach the raisin bread, which is located on the very top shelf. The young man standing almost directly beneath her is provided with an excellent view, just as he surmised he would.
Once she descends the ladder he muses that he really should get two loaves as he is having company for dinner.

As the clerk retrieves the second loaf of bread, one of the other male customers notices what was going on. Thinking quickly, he requests his own loaf of raisin bread so he can continue to enjoy the view. With each trip up the ladder the young lady seems to catch the eye of another male customer. Pretty soon, each male customer is asking for raisin bread, just to see the clerk climb up and down. After many trips she is tired, irritated and thinking that she is really going to have to try the bread herself.

Finally, once again atop the ladder, she stops and fumes, glaring at the men standing below. She notices an elderly man standing amongst the crowd staring up at her. Thinking to save herself a trip, she yells at the elderly man, "Is yours raisin too?"

"No," croaks the old man, "but it's a quiverin."
