A chicken walks into the library

It goes up to the circulation desk and says: "book, bok, bok, boook".

After reading through a page of what the International Federation of Library Associations and Institutions "Library Humor" web page, I've realized that librarians aren't very funny. but that chicken joke really made me laugh out loud for some reason. I blame it on the giddy relief that I finally finished my paper and I don't have anything due for 2 weeks.

It's better than the armadillo joke, that most people know as the horse joke

An aramadillo walks into a bar. the bartender says "why the long face?"

(i don't know why the bartender aways "says" and never "asks")
