Mike is bummed to learn Lisa's pay raise makes her the top wage earner in the family, so he lobbies his boss for just enough of a salary bump to restore him to No. 1. Meanwhile, Callie's sexually charged sister proves to be more than Ethan can handle; and Adam finally decides to deal with his bathroom phobia.

When Callie's visiting sister shows signs of overstaying her welcome, Adam scores her a job at his office, where she hooks up with the boss. Elsewhere, Ethan saves Lisa's life at a swimming pool and is rewarded with Mike's favorite college T-shirt.
