When Nana almost has a car accident because she can't hear an ambulance's siren, Susan insists that Nana get a hearing aid. This makes Nana feel old, and she becomes lethargic and uninterested in anything. Meanwhile, free from his responsibility to Susan, Jack overcompensates by indulging in more and more dangerous sports. Susan reinvigorates Nana by convincing her to go skydiving with Jack -- and Jack forces Susan to jump from the airplane as well. Meanwhile, Luis and Vicki become jealous of Maddy's super efficient new personal assistant, so they hire one. For the small amount of money Luis and Vicki can pay, they get a moron. However, Todd and Luis gloat when Maddy's assistant turns out to be a con artist who robs Maddy's apartment, steals her car and empties her bank accounts. Also, Todd makes an ill-advised attempt to establish a career as a mime-imitating passerby.
