A Chicken and a Frog are in a Library.....

The chicken picks up a book, turns to the frog and says, "Book book book booook book book book book".

And the frog says, "Reddit, reddit".

Possibly my favourite joke of all time?

Ghost Joke

Q: What did the Doctor say to the Ghost?

A: Say aaaaAAAAAAHHHHHHH

Admittedly it works better live........
