Alright, listen up, chucklehead. This joke is funny because it relies on you not realizing the girl has no arms until the punchline. The setup makes you think there's a normal reason she fell, but nope, she just couldn't hold on. You probably woulda been able to tell the girl didn't have arms if you weren't so busy looking at yourself in the mirror, you handsome devil.
