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!
Unsure what to do, the blonde quietly sneaks out of the house, drives around until her normal quitting time, and returns home without saying anything.
The next day at work, the gals get together. "That was fun," says the brunette. "We should do it again sometime."
"I met a great guy!" says the redhead.
"No way," says the blonde. "I almost got caught."
