Rebecca's One Night Stand

Lisa finally convinces Rebecca to have her first one night stand. But the always polite Rebecca violates Lisa's number-one rule by calling her date, Leo, the morning after. Now Leo is into Rebecca, so Lisa gives her sister her own unusual brand of dating advice so Rebecca can break up with him. Meanwhile, an overworked Perry decides to take a stay-cation. But doing so gets on the nerves of his unemployed roommate, Shawn, to the point that Shawn decides to get a job - any job.
