I'm thinking in the episode Vomitrocious they were making fun of George because of his nosebleeds but then being nice to Francine because of her vomiting. They are just really loyal to Francine and probably were more grossed out by the blood thing, but then Francine (who initially started making fun of George in the first place) stands up for George and points out how hypocritical they've been acting. I think Francine has a secret crush on George because she was teasing him only to invite him later for a milk shake which led to more teasing which then gave her the opportunity to show George that she really cares about him. And the others making fun of George wasn't because they were purposely being mean but rather they were just simply grossed out and only acted nicer about Francine vomiting because they were concerned that she was getting sick. :)
