The policeman in charge of testing the recruits thinks Shirley is too puny and weak to do the assault course, so Laverne helps Shirley train to prove him wrong. Laverne's policeman boyfriend is getting women volunteers together to form L.A.M.P. (Ladies' Auxiliary Milwaukee Police). Laverne is naturally selected, but then Shirley wants to try it too. Laverne tries to dissuade her but ends up agreeing as long as Shirley doesn't quit. When Shirley gets there, no sooner does she try the obstacle course than she fails at the first obstacle which happens to be a pool of water. Shirley runs out of the room soaking wet. Laverne finds Shirley at the Pizzabowl in the ladies room, and Shirley now wants to quit. Laverne calls Shirley a cream puff and storms out. Back at the apartment, Shirley apologizes and says she'll keep at it if Laverne will help her become more athletic. Laverne then trains Shirley in all the obstacle course events until the day of the test, Shirley manages all the obstacles
