Mine are Secret World of Girls and Short Story - Man is this bad easily the worst Even Steven episode in a long time. I can watch any other episode from that show, but these 2 are impossible.

I'll explain later what's yours?!

Aww! I loved The Secret World of Girls! I think the worst episode IMO has to be the one where Louis, Twitty, Tom, and Tawny start a lumberjack club or something... And then when this princess or proper girl comes over from England and Ren is hosting her or something, and Louis and Twitty take her to this grubby restaurant and she stuffs her face and gets all messy...not sure the episode names.
