Vibrator

A little old lady with blue hair entered the sex aids shop and asked in a quavering voice, "Yy-young man, dd-do y-you sell-l d-dildoes h-here ?"
The salesman, somewhat taken aback by the little old lady's appearance in his shop, answered, "Uh, yes ma'am. We do."

The little old lady, holding her quivering hands about 10 inches apart asked "D-do y-you ha-ave an-ny ab-bb-bout th-this lon-ong?"

"Well, yes ma-am, we do. We have several that size."

Forming a 5" circle with her fingers, she then asked, "A-are an-nny of t-them ab-b-bout thi-is b-big ar-round-d?"

"Well.... yes ma'am, a few of them are about that big."

"D-do aa-ny of t-them ha-ave a v-v-vibra-a-ator?"

"Yes ma'am, one of them does."

"W-w-ell th-then, h-how d-do yo-ou t-turn it off?"
