Think 'Community' but not very good and in high school. Also with a different main plot. Actually it's nothing like Community.
The epitome of Canadian teenager sitcoms from the mid '90s to early 2000s. It ran for three seasons and followed the miss adventures of a gang of high school students as they ran their school radio show.
The gimmicky characters, crazy aesthetics, and wacky "would never happen in real life" things that went on were all part of this particular breed of show's charm during the 1990s. Ms. Atoll was the sneaky, conniving bitch teacher who set out to make their lives miserable. I think every sitcom on YTV and Teletoon during this period had a character like that. Sadly I had a few of those teachers myself in high school!
Just listen to that silly theme song with the boppy synths and shitty logo:
It starred Giancarlo Caltabiano, who would later go on to be the boss on another low budget Canadian sitcom "Fries With That?" in the 2000s. I hope that guy lands a big role or something again someday, he was fantastic.
