Blind man.

Blind Man

=

A young woman has just undressed to step into the shower when the
doorbell rings. She goes to the door and says, Who is it?

Blind man, comes the reply.

So instead of going back to the bathroom for her robe, she opens the
door.

Hmmm.. nice body, lady. Where do you want the blinds?
