I came in with Halley's Comet in 1835.

It is coming again next year,

and I expect to go out with it.

It will be the greatest disappointment of my life if I don't go out with Halley's Comet.

The Almighty has said,

no doubt: 'Now here are these two unaccountable freaks;

they came in together,

they must go out together.'
