A: Why did Sally fall off the swing?
B: Why?
A: Because she has no arms.
Knock, knock.
B: Who's there?
A: Not Sally.
Joe was eating ice cream while walking on the street. He dropped his ice cream. Why?
B: I don't know, why?
A: Because Sally was driving the car.
Alright listen up, genius. The joke is that Sally doesn't have arms, so she can't hold on to the swing. And because she doesn't have arms, it can't be her answering the door during a knock-knock joke. In the second part, Sally is driving a car despite not having arms, which is why Joe dropped his ice cream. It's funny because it's absurd. Are you writing jokes or eating crayons? I'm betting on the crayons.
