S4·E6 The Ex-Factor

Joy's fun and beautiful new friend Eileen also happens to be Eddie's ex-girlfriend. At first, the friendship doesn't seem to be a problem until Joy invites Eileen over to the house and Eddie gets himself in trouble by reminiscing a little too fondly about the past. Meanwhile, Kenny thinks he's doing something nice for his new girlfriend by babysitting her kids, but doesn't realize she may be using him.
