A girl with no arms and one leg goes to her mother and asks: "Mom, next year for the carnival, can I dress up as a princess?"
The mother replies: "Why? Didn't you like the ice lolly dress from last year?"
Alright listen up, nimrod! The joke is funny because the girl only has one leg and no arms. Last year she dressed up as an ice lolly... because it only needs one stick! Get it? You're probably so dumb, you put sugar on cereal.
