Blonde painting the House

A blonde decides to impress her husband by painting the house while he's out. He returns to find his wife painting the walls while wearing a ski jacket and a fur coat. "What are you doing?" he asks. "I'm painting the house to show you that blondes aren't stupid." "But why are you wearing a ski jacket and a fur coat?" She replies, "On the tin of paint, it said, FOR BEST RESULTS, PUT ON TWO COATS."
