A blonde goes into a kitchen store and says to an assistant "Can i buy that TV please?"
The assistant says "Sorry we don't serve blondes."
So the blonde goes out and gets her hair dyed and then comes back and says, "Excuse me can i buy that TV please?" and the assistant says "No, because we still know who you are."
So the blonde goes out and gets plastic surgery.
She then comes back and says
"Excuse me, can I buy that TV please?" and the assistant says, "No, because it's a microwave!"
