"Leaving Early" joke

Three women all worked in the same office, with the same female boss. Each day they noticed that the boss would leave work early.
One day, the women decided, that when the boss left, they would leave right behind her. After all, she never called, or came back to work, so how would she know they went home early.
The brunette was thrilled to be home early. She did a little gardening, played with her son, and went to bed early.
The redhead was elated to be able to get in a quick workout at the gym before meeting her dinner date.
The blonde was happy to get home early to suprise her husband. But when she got to the bedroom,
she heard a muffled noise coming from inside.
Slowly and quietly she cracked open the door, and was mortified to see
her boss in bed with her husband!
Gently she closed the door, and crept out of the house.
The next day the brunette and the redhead planned on leaving early again and asked the blonde if she was going to go with them.
"NO WAY," the blonde exclaimed, " I ALMOST GOT CAUGHT YESTERDAY!!!"
