There is a blonde, brunet and red head. They all work in a shop were the blondes husband is the owner. The husband leaves to go home 3 hours early every day. One day the 3 works decide to lock up the store and go home a hour early. When the blonde arrives home she sees her husband having sex with another women but he doesnt see her so she goes out. The next day the 3 girls ask each other if they want to leave work an hour early again and go to home but the blonde says "no i almost got caught yesterday".
