Things get awkward for Shirley when she realizes Mike, the peppy and handsome guy she's been seeing, is seven years younger than her. The girls joke around about the difference between their nearly-thirty selves and Mike, who's not even twenty-one yet. When Mike calls up, asking to take the girls to his frat's big mixer, the giddy gals agree to go. Laverne even offers to head out on a blind date with Mike's awkward but gentlemanly friend Lyle. Laverne and Shirley quickly learn that Mike and Lyle aren't full members of the frat yet - just pledges. Ergo, the girls are forced to dance with all 30 brothers in the hope of fulfilling their duty as pledgees and making them brothers. Can Laverne & Shirley survive the ensuing dance-a-thon?
