What is the story behind hobbit forming jokes in irregular web comic?

You're likely referring to the webcomic "Irregular Webcomic!" by the artist "The Oatmeal". While it's true that the comic features a character named "Hobbit", he doesn't specifically "form jokes". He's a generally grumpy, but lovable character who often finds himself in absurd situations and reacts with his own unique brand of sarcasm and bluntness.

The story behind Hobbit's creation is not explicitly stated in the comic, but he is depicted as a regular visitor to the "Irregular Webcomic!" universe and frequently interacts with the main character, "The Oatmeal".

It's important to note that the comic is known for its humor, but it's not specifically focused on Hobbit telling jokes. Instead, the humor comes from the interactions between different characters, the absurd situations they find themselves in, and the unique way The Oatmeal uses words and images to create a comedic effect.

If you're looking for specific jokes related to Hobbit, you might need to provide more context or specific examples from the comic.
