Joke

A blonde walks into a shop and gets one of the staff to help her find a TV. She finds one and says: "Can I buy that TV please?"

Staff guy: "No I don't serve blondes!"

Blonde: "Wait here!" She runs of, dyes her hair black and comes back in and says: "Can I buy that TV please?"

Staff guy: "No I don't serve blondes!"

Now the blonde is getting confused so she goes and dyes her hair red and comes back in and says: "Can I buy that TV please?"

Staff guy: "No I don't serve blondes!"

Blonde: "Why do you keep on calling me a blonde?"

Staff guy: "Because that's not a TV that's a microwave!"
