So I have a general policy of “never explain the joke”, but this time I will: the treacherous banana is an in-joke that references a book on childcare from 1897, written by a ridiculously bigoted man who had some really weird ideas about raising kids.

Oh, they’re fine! That was a nice soft landing, nothing could possibly have gone—
