Mind Your P's and Q's

Pause, Quickly,
Prepare to go.
Quietly Quoting,
edgar allan Poe.

Perfect, Quantum
Particle Physics show.
Quark's strangeness
is charming don't you know?

Perhaps, Query Politely,
Prime Professors in a row.
Quantify, Precisely,
how to run the show.

Perpetual Quartz,
Pulsating Pendulum,
Past, Present, future,
Perfect time bestow.

Purchased Quail,
Quality, Quid pro quo,
Purchase Punnets, Pears
and Puce and Quorn, just so.

Pause, Quickly
Prepare to go.
Quietly whisper
"i'm Puddled, so you know."
