And...
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. The boss will never know."
The next day, they all leave right after the boss does. The brunette gets some extra gardening done & the redhead goes to a bar. The blonde goes home and finds her husband in bed with the female boss! The blond quietly sneaks out of the house for while, then returns home at her normal time.
The next day, the brunette says, "That was fun. We should do it again sometime."
"No way," says the blonde. "I almost got caught!"
