Wyatt laments that his grandmother doesn't have the energy that she used to. Lisa zaps Nana who starts to pull the energy from everyone she meets and ages people including the boys.
After Chett is struck by lightning, Lisa makes him invincible. Chett then becomes the superhero Star Spangled Butt Kicker and fights crime until the invincibility wears off at the wrong time.
After Gary and Wyatt have a falling out, Lisa zaps them into their favourite TV series "The Sci-Fi Zone" which was why they became friends in the first place.
