PBF - Dick (webcomic)

From Perry Bible Fellowship - https://pbfcomics.com/comics/dick/

See, it's funny because...well, it's probably only funny in a really, really dark way.

There's this guy who seems to be captaining a whaling ship. We'll call him Ahab. 

He seems to have spotted something, a whale, we assume.

He takes a drink from the colorful bottle in his hand...then drinks from a series of very colorful, seemingly modern bottles.

We close by seeing the whale dead in an ocean littered with plastic waster.

See, it's funny because we're killing our ocean's life by polluting the water with plastics.

Get it?

As an aside, be warned that many other cartoons on PBF are less school-appropriate. Browse at your own risk. They are, however, often hilarious in very dark ways.
