A brunette walks into in a porn shop:
She asks, "How much for the white dildo?"
He answers, "$35."
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."
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 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!"
