I think it's funny because it plays on a common but often overlooked moment and exaggerates it for comedic effect. The character's attempts and struggles to reach the toilet can be quite amusing.
He could be reaching for a book or a toy. Maybe it's something he really wants or needs.
It could be in a store or at home. Maybe he's looking for the right fit or trying to decide on a style.
Well, a pee cartoon might be funny if it plays with absurdity, like having the pee do something completely crazy. Or it could be the way it mocks common situations and turns them into something hilarious through pee-related antics. Sometimes, it's the simplicity of the humor that gets you laughing.
He might be making an announcement or trying to get people's attention for something important.
Maybe he's just lonely and looking for some company in that vast space.
Maybe he's really angry and has lost his mind.
Maybe they want to have some fun or show off their skills.
Often, in such cartoons, the small guy might first observe the big guy's weaknesses and then plan a strategic attack. Sometimes, they might get help from friends or use the environment to their advantage.
Well, the guy could be deciding if the style of the jacket suits him or maybe just having some fun trying different looks. Also, he might be imagining how he'd wear it in various situations.
Maybe he's lonely and looking for companionship.
