I am still trying to find an episode of Happy Days, where for some reason Mr. Cunningham is shown in the principal's office. It shows the daughter Joanie outside the door crying. I can remember it must have had something to with gangs, because Mr. Cunningham says this is end of the gang. Can anyone remember an epsiode like this?

Sounds like an interesting episode, but I don't think it exists.

That's not the episode where Joannie takes up smoking, is it?
