Captain Underpants/YMMV


 * Complete Monster: Mr. Krupp seems to be this from George and Harold's point of view.
 * In Book 8, it is shown that the entire school faculty is this to the rest of the student body.
 * Nausea Fuel: Pretty much inevitable in Toilet Humour-themed series, but the Bionic Booger Boy gets special mention. His descriptive introduction has George yell at the narrator for making everyone sick.
 * Squick: A grown man runs around in his underwear with two ten-year-old boys.
