When Lisa uses the stopwatch at the end of "Stop the World, I Want to Goof Off", the things that suddenly happen to the other members of the family are:
-The upper portion of their bodies become rockets and zoom around.
-They turn into bobbleheads.
-They turn into 'TV Guide' covers.
-They turn into the Fantastic Four.
-They return to normal, but are playing with hula-hoops.
