SpongeBob SquarePants wears completely square brown pants

For reasons defying all known laws of marine biology and underwater tailoring, a deeply optimistic sea sponge chooses to dress like a 1950s middle-management bank teller.

It’s a beautifully absurd commentary on how deeply animated characters are chained to their iconic silhouettes.
