Alright listen up, chucklehead! So, Little Jim here, he's trying to make a quick buck by farting for money, right? But instead of a polite toot, he ends up crapping his pants. Then, because this joke was written by a toddler, he smears the poop on the bullies. I am not sure why this is funny to you, but you do you. Don't forget to wipe!
