I have always been fond of Shakespeare's plays and sonnets. It goes back to Year 10 (then Fourth Form), when my English class studied Macbeth. Being brim full of witches, murder and revenge, it is a good play for adolescents to study as an entry point to the Bard. We read King Lear and Hamlet in senior years and then at university, another swag of his works. Later on I taught them myself, a challenge, I can assure you.

The following sign was allegedly posted on an academic's door, presumably one teaching in the humanities. If you know Hamlet, then it is quite witty. But if you don't, then it will pass you by without a titter. I wonder if folks will have a laugh at such references in 50 years time, or will this kind of humour become the preserve of a tiny minority.
