The Ugly Barnacle is a very short story that Patrick tells SpongeBob in the episode "Something Smells." It is meant to boost SpongeBob's self-esteem to make him feel better about his appearance, but it only makes him feel worse. Because of this, Patrick insists they scream on top of SpongeBob's house to get rid of his depression instead.
Once there was an ugly barnacle.
He was so ugly that everyone died.
