okay so, I just found out about this anime called sayonara zetsubou sensei(or goodbye, mr. despair) and I want to know if it's clean... I did watch the opening theme and it made it look like not a good show, but I read a description for it and it sounds hilarious. I really want to watch it but I just don't know if it's clean... Has anyone watched this show and can tell me if its okay?
P.S. I'm NOT okay with gay/lesbian relationships or sex(comments or references are okay as long as they're to a minimum)
