A woman calls a Contractor to her house to give her
a bid on painting the interior of her house.
She takes him into the first room and tells him that
she wants it painted pale green.
The contractor writes something down on his notepad,
goes over to the window and yells down "green side up".
The homeowner takes him into the next room and tells
him that she would like it painted rose colored.
The contractor again notes it on his note pad, goes
over to the window and opens it. He then yells down
"green side up".
The woman was curious, but continued to show him the
rest of the house. In each room the contractor notes
her color choice on his notepad and yells out the
window "green side up".
When the homeowner had completed the tour, she asked
the contractor why he always yelled "green side up"
when she told him her color choice, when the colors
were all different.
He laughed and replied "I have a crew of blondes across
the street laying turf."
Blonde joke
EDIT: well the frowning one works.
