Confusion

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

Guy: “$35 for the white, $35 for the black.”

Blonde: “Hmmm….how much is that plaid one on the shelf?”

Guy: “Well, that’s a very special dildo…it’ll cost you $150.” 
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?” The salesman responded,

Guy: “I think I did pretty good, I sold one white dildo, one black dildo, and I sold your thermos for $150!”
