A blonde walked into a store, turned to the store clerk and said"I'd like to buy that TV"
He said"I'm sorry, we don't sell TVs to blondes"
She walks out and walks back in with a brunette wig on
She again says to the same store clerk"I'd like to buy that TV"
He says again"I'm sorry we don't sell TVs to blondes"
She walks out and once again walks back in with a red wig on
She once more asks the same clerk"I'd like to buy that TV"
He once more says"I'm sorry, we don't sell TVs to blondes"
she whips off the wig and says to him"How do you know its me and why won't you sell that TV to me?"
he stares at her and says"Because, that's a microwave"
