A blonde, a brunette, and a redhead all work at the same office for
a female boss who always goes home early.
"Hey, girls," says the brunette, "let's go home early tomorrow. She'll
never know."
So the next day, they all leave right after the boss does. The
brunette gets some extra gardening done, the redhead goes to a bar,
and the blonde goes home to find her husband having sex with the
female boss! She quietly sneaks out of the house and returns at her
normal time.
"That was fun," says the brunette. "We should do it again sometime."
"No way," says the blonde. "I almost got caught."
