A blonde walks into a hardware store, and is looking for a new television. The store assistant approaches her and says, "I'm sorry madam, but we don't serve blondes." So she goes home, has a breast reduction, and dyes and cuts her hair. She goes back to the store, and asks the assistant, "I'd like to buy this television please". The store assistant replies, "sorry madam, we don't serve blondes." "How did you know?" she said.
"Because that is a microwave, not a television!"
