Three women, a brunette, a red head, and a blonde, all work together in an office. Every day they notice the boss leaves work a little early. So they meet together and decide that today when the boss leaves, they will leave early too. The boss leaves and do do they.
The brunette goes home and straight to bed so can get an early start the next morning. The red head goes home to get in a quick work-out before her dinner date. The blonde goes home and walks into the bedroom. She opens the door slowly and sees her husband in bed with her boss, so she shuts the door and left.
The next day, the brunette and the red head are talking about going home early again. They ask the blonde if she wants to leave early again. "No," she says, "yesterday I nearly got caught!"
