"Sorry, we don't sell to blondes," he replied.

She hurried home and dyed her hair, then came back and again told the salesman, "I would like to buy this TV."

"Sorry, we don't sell to blondes," he replied.

"Darn, he recognized me," she thought.

She went for a complete disguise this time: a brown curly wig, big baggy clothes, and big sunglasses. Then she waited a few days before she approached the salesman again and said, "I would like to buy this TV."

"Sorry, we don't sell to blondes," he replied.

Frustrated, she exclaimed, "How do you know I'm a blonde?"

"Because that's a microwave," he replied.
