9:47 could've been an alternate ending which could extend into a movie. For example, Junior was taken to Area 51 with the other Aliens, and he needs to find a way to escape, to make everything more thrilling, Junior could fight some of the aliens and obtain abilities.
SOLID episode, it was relatively quite unpredictable I also love how “GET YOUR FEET OUT YOUR MOUTH” is still being used years later, and is still funny.
