Astronomer Royal, Edmond Halley
Confided (back when we were pally),
‘On sighting a comet
I gen’rally vomit;
And shooting-stars drive me doolally.’

Not an ideal companion, then, on our seasonal expedition to the heath to view The Perseid Shower, and to join in the midnight incantations whereby witches implore these cosmic projectiles to validate their hitherto-purposeless trajectories by hailing down on the skulls of this planet’s most infamous leaders.
