A blonde goes in to a hardware store, walks up to the counter and asks, Can I buy that TV?

The guy replies No so the blonde goes outside and dyes her hair brown and goes back in and asks, Can I buy that TV?

Again, the guy replies No so she goes back outsite and dyes her hair black, then goes back in and asks, Can I buy that TV? Not surprisingly, the guy replies No again, so in desperation the girl goes back outside and shaves her hair completely off.

Finally, she walks back in the store and asks Can I buy that TV?, to which the guy replies No.

Frustrated, she asks Why wont you sell that TV?

The guy says, Two reasons, actually. First, youre the same silly blonde who keeps coming in here with dyed hair, and second, its a microwave!
