I have a theory/headcanon that “Twinky” is actually Calvin’s surname, since I noticed it’s common for bullies in fiction to refer to their victims by their last name.
I don’t remember, but it involved Phoebe teaching Marigold how knock-knock jokes work, and Phoebe ended up being shocked when Marigold said “Who’s there?” due to her using a contraction
If this had come out a few decades prior, Emily would’ve spanked Phoebe and made HER butt hurt more.
Thankfully, that’s considered child abuse nowadays.
