Krupp sees this as the opportunity to move them into separate classes, effectively destroying their friendship. He's unable to catch them in the act so he has to endure their constant misadventures until the school tattletale Milton (Jordan Peele) records them messing with his project for the science fair. Principal Krupp (Ed Helms) definitely is in the camp that believes that these two are a menace and he makes it his goal to put an end to their shenanigans.
To any adult looking in, they're a pain to deal with but they bring life to their dull and dreary environment. Moving back to George and Harold, their friendship is as close as it gets and they spend their days making these comics and pulling pranks on the faculty. Their favourite character is Captain Underpants and we get an introduction to his comic origin in the beginning. *Minor Spoilers Ahead* George (Kevin Hart) and Harold (Thomas Middleditch) are two elementary school kids that write and animate comic books in their tree house.
