A blonde woman went into a well known department store which had advertised a sale on televisions.
She asked the salesperson, "I'd like to buy this t.v. if I could please."
He replied, "I'm sorry, we don't sell to blondes".
So, she left upset and went home and decided she wanted to go back and buy the t.v. She put on a wig to make her brunette.
When she returned to the store she asked if she could buy the t.v again and the salesperson said that they don't sell to blondes.
Again she left upset and went home and put on a complete disguise. She put on a moustache and beard, cut her hair into a man's hair style and dyed it and wore a suit.
Again she returned to the store and asked if she could buy the t.v.
The salesperson replied that they don't sell to blondes.
She immediatley exclaimed, "I've put on a complete disguise hiding the fact that I'm blonde, how did you know?"
The salesperson replied, "Because that's a microwave."
