Quinn's pet alpaca, Otis, is depressed because he misses her, leaving her feeling depressed as well. The girls then decide to try and cheer her up by throwing an alpaca-themed party. However, this only made her miss Otis even more and she left PCA to meet with him, which could get her suspended as it is the middle of the semester. Meanwhile, the guys make a bet to see who can go the longest without saying anything containing the letter 'S' and the person who loses has to run across the campus wearing nothing but a bikini top, a hula skirt, and a flashing red helmet.

The Dean bans coffee carts on campus after an accident involving his wife, resulting in a war of the sexes when the girls and guys each try to come up with a scheme to circumvent the new rule.
