A guy is walking through downtown and passes a porn shop that his buddy owns. He decides to go in and say hi.

He walks in and his buddy Jim is behind the counter. When Jim sees his old friend, he says "any chance you could look after the shop for a bit, I haven't had lunch yet". "No problem, go grab some food" the guy says.

About 10 minutes go by and a white lady walks into the shop. "How much for that white dildo?" She says. "Uh, the white one... $10". She says okay and he wraps it up, she pays for it, and she leaves.

A little while later a black woman comes in the store. "How much for that black dildo?" she asks. "Uh, the black one... $20". She says okay and he wraps it up, she pays for it, and she leaves.

About 20 min later a woman walks in and asks "how much for that plaid dildo?" "The plaid one? Uh $50". She says okay and he wraps it up, she pays for it, and she leaves.

10 minutes later Jim comes back in and asks how business was while he was out. "Not bad; I sold a white dildo to a white lady for $10, a black dildo to a black lady for $20, and your thermos to a russian lady for $50!"
