Jackie's Cheese Squeeze - S4.E19

Eric catches Jackie kissing Todd, her boss, but instead of telling Kelso, he holds it over her head. Jackie decides to tell Kelso about it herself, as well as telling him that Eric knew all about it. Both of their plans backfire on them. Kitty feels neglected and worries about becoming a Corvette-widow when Red spends all his time with his new car.
