Funny thing to do when people make fun of you?

So I just started a new school this year and most of the girls there hate me for absolutely no reason. They all wanna fight me for no reason. Even though they would like murderr me . They call me names everyday and write mean things about me in almost aaalll the textbooks. They say things to me like hey ugly, fishy fishy, bug eyes, fish lips and godd just things I cant even say. Everything they say is about me. Everything they write is about me. There myspace status’s are alll about me. Basically there whole world revolves arount me. But yeah I think the whole thing is actually quit funny(: like I loveee all the attention they give me but really everydaay since school started ?! Like come on ! Sooo yeah some of the things they say to me I just agree with them and laugh . But what are some funny things I can say to them like when they say things like you ugly, I’ll be like yup I guess I am with a smile on my face. But what are some other things I can say to them not to be rude but just to agree with them and be funny so they dont think I dont care ? Please helppp its gettin worse and worse. And I cant be a snitch or anything. Soo thats outta the question.
