A blonde walks into a porno shop:

She asks, "How much for the white dildo?"
He answers, "35 bucks"
She: "How much for the black one?"
He: "$35 for the black one, $35 for the white one."
She: "I think I'll take the black one. I've never had a black one before." She pays him, and off she goes.

A little bit later a black woman comes in and asks "How much for the black dildo?"

He: "35 bucks"
She: "How much for the white one?"
He: "$35 for the white one, $35 for the black one."
She: "Hmmm... I think I'll take the white one. I've never had a white one before..." She pays him, and off she goes.

About an hour later a young blonde woman comes in and asks, "How much are your dildos?"

He: "$35 for the white, $35 for the black."
She: "Hmmmmm... .how much is that plaid one on the shelf?"
He: "Well, that's a very special dildo... it'll cost you $165."
She: She thinks for a moment and answers, "I'll take the plaid one, I've never had a plaid one before...." She pays him, and off she goes.

Finally, the guy's boss returns and asks, "How did you do while I was gone?"

To which the salesman responded, "I did really good, I sold one white dildo, one black dildo, and I sold your thermos for $165!"
