The Librarian

A pair of chickens walk into a public library, find the librarian and say, "Buk Buk BUK".  The librarian decides that the chickens want three books, and promptly gives them some. Without further ado, the chickens walk out.

Around midday, the two chickens are back and looking quite annoyed. One leans over to the librarian and says, "Buk Buk BuKKOOK!"  The librarian decides that the chickens want another three books and promptly gives them some more. The chickens leave as before.

About an hour later the two birds march back in, approach the librarian looking very angry now and are nearly shouting, "Buk Buk Buk Buk BUKKOOOOOOK!"

The librarian is now starting to get worried about where all her stock is going. She decides to give them more books but also to follow them and find out what's happening.

So she followed them out of the library, out of town, and into to a park. At this point, she hid behind a tree, not wanting to be seen.

She saw the two chickens throwing the books at a frog in a pond, to which the frog was kept repeating, "Rrredit Rrredit Rrredit..."
