Fraternity Vacation (1985)

"Astronomy major Wendell Tvedt has studied galaxies, charted planets and pondered the universe. But in Palm Springs, he'll encounter his first full moon."

A nerd gains the friendship of two of his frat brothers when his dad offers them his condo for the week in Palm Springs, and also offers the fraternity a hot tub and jacuzzi if they can help his son find a girl. They meet two guys from a rival fraternity, and make a bet on who can nail the Designated Babe first.
