Ode to the Multiple Universes by Terry Pratchett

I do have worlds enough and time

to spare an hour to find a rhyme

to take a week to pen an article

a day to find a rhyme for particle.

In many worlds my time is free

to spend ten minutes over tea

And steal the time from some far moon

so words can take all afternoon,

Away beyond the speed of light

I’ll write a novel in one night.

Aeons beckon, if I want em

but I cant have em, cos of Quantum
