OH F**K I DIDNT THIK ABT THAT (IN THE EPISODE WHERE HE TEACHES DRAMA HE LITERALLY CALLS HIMSELF 'PROFESSOR P' ,WHICH IS A REF TO THE CAPTAIN UNDERPANTS MOVIE WHEN PROFESSOR POOPYPANTS WAS INTRODUCING HIMSELF)

And he also wears a brown outfit

I have yet to see that episode

You should watch it it's 'Mr puzzles Teaches drama class'
