> knock knock … porcupine who? Porcupine bulldozer - makes no sense why those things belong together and that’s what makes it funny. Then we’ll laugh and he'll ask me knock knock and come up with something just as ridiculous

Apparently when the older of my two brothers was fairly young, he would tell knock-knock jokes where the punchline was always the phrase "smashed into toothpaste". "Knock knock!" "Who's there?" "Elephant?" "Elephant who?" Elephant _smashed into toothpaste_!" My parents weren't sure exactly what he meant by that (maybe he heard about something being "ground into a paste" and assumed that toothpaste was made in the same way?), but it became a family in-joke, and even though he had stopped by the time I was old enough to converse, I'm still just as familiar with the form.

A similar family meme came from my dad playing a basic word game with my older brothers once when I happened to be present as a toddler. My dad would prompt them in the form of "one <X:singular>", and they were supposed to respond with "two <X:plural>", like "one sheep...?" "two sheep" or "one ox...?" "two oxen!" Not understanding the pattern, I interjected at one point with one of my own: "one juice, two lava!" To this day, none of us are quite sure what I meant by this (including me!), but it was memorable enough that it's the only part of this game that we remember.
