A large green frog hops into a library, jumps up on the reference counter and says to the librarian, "I want an interlibrary loan."

The librarian says, "You'll have to see the Head of ILL. Her office is down the hall and the name on the door says "Patricia Wack."

So the frog hops off the counter, down the hall and to Mrs. Wack's office.

He jumps up on her desk and says, "I want an interlibrary loan." Mrs. Wack, quite puzzled, gives the standard line, "We must have something to secure the loan, a library card or some collateral."

At that the frog pulls out a ceramic lion, places it on her desk and repeats that he wants a loan.

So Patricia picks up the ceramic lion, goes in to the Library Director's office, places the ceramic lion on his desk, and tells him, "I have this frog in my office who says he wants a loan, and this is what he has to secure it. I don't even know what this thing is."

The Librarian looks at the ceramic lion, looks at Mrs. Wack, looks back at the ceramic lion and finally says, "It's a knick-knack, Patty Wack. Give the frog a loan."
