|I Was a Teenage Thumb|
George Ebenezer Thumb and his wife Prunhilda desperately want a son, so they are granted a thumb-sized one by the wizard Ralph Merlin. But after being snatched by the family cat, and then by a large bird, the baby manages to escape, then falls victim to a giant fish caught by a knight, which is then brought to King Arthur himself for a meal. The baby then is noticed by Arthur when he cuts open the fish. Arthur makes him a knight, and he eventually marries and has a son the size of his thumb, who has a son the size of his thumb, and so on.
Versions of this cartoon commonly shown on television censor King Arthur's line after he finds the thumb-sized baby in his fish, removing the profane word "ass." The scene is edited in at least three different ways depending on the channel:
- On ABC and Nickelodeon, King Arthur's line after he finds the thumb-sized baby in his fish, "Morty, you ass! This fish is full of people!" was edited to remove "you ass" (so now the line goes, "Morty...this fish is full of people!"). It should be noted that ABC used to air this uncut on Saturday morning TV between 1985 and 1989. The "you ass" edit wasn't made until 1998.
- Rather than edit the "you ass" in "Morty, you ass! This fish is full of people!", Cartoon Network and Boomerang's version cut the scene featuring that entire line.
- In the version shown here from Russian channel 2x2, the fish cutting scene remains, but the line is muted.
