The manatees were hard at work in their aquarium trying to come up with a new shitty script for an episode.
Suddenly as the rolled some balls into the appropriate slots they lined up to form "The Captain of Underpants"
Captain Underpants the script writers thought, then the episode aired.
"Hey honey" said Peter Griffin, "that reminds of the time I met Captain Griffin while high on LSD"
Cut to scene
"I'm smoking LSD" Peter Griffin mumbled to himself, "Oh hey Captain Underpants"
Wow Cartman said, another typical shitty Family guy episode.
