"A blonde decides one day that..." joke

A blonde decides one day that she is sick and tired of all these blonde jokes
and how all blondes are perceived as stupid, so she decides to show her
husband that blondes really are smart. While her husband is at work, she
decides that she is going to paint a couple of rooms in the house. The next
day, right after her husband leaves for work, she gets down to the task at
hand. Her husband arrives home at 5:30 and smells the distinctive smell of
paint. He walks into the living room and finds his wife lying on the floor in
a pool of sweat. He notices that she is wearing a ski jacket and a fur coat
at the same time. He goes over and asks her if she is OK. She replies,
"Yes."
He asks what she is doing. She replies that she wanted to prove to him that
not all blonde women are dumb and she wanted to do it by painting the house.
He then asks her why she has a ski jacket and a fur coat on. She replies that
she was reading the directions on the paint can and they said, "FOR BEST
RESULTS, PUT ON TWO COATS."
