Blind Man and Window Installation

A woman is in the shower and hears a knock at the door. Wondering who it could be, she turns off the water and yells, "Who is it?"

From outside, she hears, "Blind man!" The woman thinks this is weird, so she says again, "Who is it?" "Blind man!" The woman shrugs and goes to the door without bothering with a towel. She opens the door, and the guy on the other side smiles, looks her up and down, and says, "Great body, lady, but where do you want me to install these blinds?"
