Mike and Lisa hire a hot young babysitter for Tommy, but the skimpily clad teen brings more teen angst to the household than the Rileys can handle. Meanwhile, when a disabled food-delivery guy (guest star Daryl Chill Mitchell) accidentally intrudes upon Callie's naked dance party, Adam finally confronts her about her habits in the apartment. But when they find out the delivery guy is also a computer whiz and decide to hire him, Adam learns a lesson in indecent exposure the hard way. Also, Mike and Adam try to convince Ethan to get rid of his hideous necklace, but he finds comfort in a new fling who does not see the necklace the same way.
