I would imagine

that the looptape of a two-year old's idea of a knock knock joke would go a little something like this:


2 year old: "knock knock"
me: "Who's there?"
2 year old: "nana"
me: "nana who?"
2 year old: "knock knock"
me: "Who's there?"
2 year old: "nana"
me: "nana who?"
2 year old: "knock knock"
me: "Who's there?"
2 year old: "orange"
me: "orange who?"
2 year old: "knock knock"
me: "Who's there?"
2 year old: "nana"
me: "nana who?"
2 year old: "knock knock"
me: "Who's there?"
2 year old: "Boo"
me: "Boo who?"
2 year old: "knock knock"
me: "Who's there?"
2 year old: "nana"
me: "nana who?"
2 year old: "knock knock"
me: "Who's there?"
2 year old: "knock knock"
me: "knock knock who?"
2 year old: "Who's there?"
me: "I don't know. Who's there?"
2 year old: "knock knock"

me: initiate distraction and redirection tactics
