Okay, so there was this show my sister and I used to watch all the time in the early to mid 90's. It was a kids show and was about this group of teenagers going to a school called edgar allen poe high. They got into scary/comedic situations involving the supernatural. One episode I can remember particularly well is when the cafeteria lady is replaced by a monster that tries to turn the student body into bugs by feeding them delicious addictive food that has bugs and larvae baked into them and the day is saved when one of the main characters (a guy with short dark hair) discovers that mustard kills the bugs taking over the human bodies. I realize I can remember quite a bit about this but I can't remember the name of the show for the life of me but I'm pretty sure it ended with the word "High".
Anyone that can figure this out for me would be my hero forever.
