Surrounded by Cuckoos, but I was the crazy one

I don't know what this fuckin means...If someone else is a Cuckoo.... then how am i the crazy one...am i crazy because i am not a cuckooo... i would not want to be a cuckoo anyway..

although when I first read this topic i thought of this song called Dark Blue by  Jack Mannequin.... He says "Dark Blue , Dark Blue, Have you ever been alone in a crowded room."
 so in a way.... I think I know , Mr. McCarthy, what you want me to write about.. Like if i was ever in a place where everyone thinks something different even though I might be right but I'm the weird one..... Yea i just don't know how to write about that.... sorryyyy.
