“Ranger declined the butterscotch pudding, not wanting to disrupt the consistency of his blood sugar level. I had two puddings and coffee, choosing to keep my pancreas at peak performance. Use it or lose it is my philosophy.”

The Hasty-Pudding (1793)
Context: Despise it not, ye Bards to terror steel'd,
Who hurl'd your thunders round the epic field;
Nor ye who strain your midnight throats to sing
Joys that the vineyard and the still-house bring;
Or on some distant fair your notes employ,
And speak of raptures that you ne'er enjoy.
I sing the sweets I know, the charms I feel,
My morning incense, and my evening meal,
The sweets of Hasty-Pudding. Come, dear bowl,
Glide o'er my palate, and inspire my soul.
