A guy gets a job as a salesman at a dildo store. First day a brunette walks in and asks: "How much for the black dildo?" He tells her: "$50 for the black one, $50 for the white one." She leaves without buying anything. Then a redhead walks in and asks him: "How much for the white dildo?" He replies" "$50 for the white one, $50 for the black one." She doesn't buy anything either.
Finally a blonde walks in and asks him" "How much for a dildo?" He answers: "$50 for a black one, $50 for a white one." Then she points and asks: "How much for the plaid one on the shelf behind you?" He says" "Oh that's a very special one, that's $250." She buys it.
At closing, the manager asks the guy: "So how much did you sell today?" The man tells him: "No dildos. But I did sell your old thermos for $250."
