A lady of obvious culture walks rather shyly into a sex toys store to buy something for her self.
"How much is that one there?" She asks?
"10 bucks," the clerk says.
"How about that huge one there?" she inquires.
"That's 25 dollars," the clerk responds.
"Ooooooooooooooh. How much for that giant plaid one right there on the counter?" She asks breathlessly.
"That one? It's fifty dollars," The clerk says.
"I'll take it!"
A short time later, the manager walks in and asks the clerk how sales are going that day.
"Pretty slow," he said, "But I DID sell my thermos to a lady for 50 bucks."
As I had no good puns, I figured a sex toy joke would work instead.
