The Bardwell Caper (2) - S6.E16

The girls recruit Lenny, Squiggy, and Carmine to help them pull off this mission. Lenny and Squiggy will drive the getaway car, and act as lookouts, while Carmine, Laverne, and Shirley will sneak through the air vents, and make their way into the boss's office. They will carefully maneuver around the alarm system, retrieve the letter, and be on their way. No one shall be the wiser.

Of course, when they try to put the plan into action, our heroes run into some obstacles along the way, and quickly realize that this isn't going to be as easy as they thought.
