As much as I love “Exit, pursued by a bear,” I think it overshadows a few of Shakespeare’s other wonderfully weird stage directions. For example, Richard III features this peach of a stage direction before Richard receives Hastings’ severed head:
“Enter GLOUCESTER and BUCKINGHAM, in rotten armour, marvellous ill-favoured]”
Like, for a guy who seldom bothers who write stage directions, he takes the time to specify that not only is their armor rotten, they look bad in it.
I also like “He goeth down” from Romeo and Juliet.
