Plot

In order to raise the money to go to a cocktail party, the girls sign up to be paid volunteers for scientific experiments.

Shirley gets an invitation to a cocktail buffet party with businessmen in suits at the Hotel Pfister from Mrs. Babish, but Laverne reads the small print: RSVP (which Shirley says is French for "respond so very promptly"). Laverne sees that $20 is the admission price. The girls are broke--as usual--so they canoodle out of Lenny and Squiggy the name of the place where they earn part-time cash. The girls volunteer to be paid subjects for scientific experiments (guinea pigs) at the Institute of Behavioral Sciences. But with Laverne in a sleep study and Shirley in a nutrition study, will the girls be in any shape to enjoy the party?—LA-Lawyer
