“Have you heard about Sally?” an “Anti-Joke”

“Why did Sally fall off the swing? Because she had no arms. Knock Knock? Who’s there? Not Sally.” This joke is popular among middle-schoolers and high-schoolers in Broomfield, Colorado, and was performed for me by a 12-year-old boy and a 17-year-old girl. They refer to it as an “anti-joke” where two jokes are told in series, with the first being “lame” and the second being the punchline.
