What naughty or creepy subtexts or easter eggs have you detected in "PG" movies/shows/films? What are your favorite well-known subtexts or easter eggs?
I liked the penguins doing the "69" in Happy Feet.
I wouldn't consider this as subtext or an easter egg, but I found it suspicious. A few weeks ago, I did a service project reading books to elementary kids. One of the books had a main character named "Percy". That's not even a common or modern name.

I had to hold my giggles everytime I said that name, and the teacher giggled also. I bet the author did that on purpose to make the grown ups laugh while telling the story.
