A man went into a library to get a book on how to commit suicide.
The librarian said, "No, you won't bring it back."
Alright, listen up, you cotton-headed ninny muggins! This joke is about a dude trying to check out a book on how to off himself from the library. But the librarian ain't having it. Why? Because dead people tend not to return books. It's dark humor, see? Also, I bet you are the type of person that uses Comic Sans.
