For whatever reason, I was suddenly struck with a flash of memory - I worked briefly as an operator for a catalog phone order center, and it was customary for us to give the caller his or her order number upon completion of the transaction... I took this as an invitation to be clever.

The order numbers were a single letter followed by 6 or 7 numbers, and we were encouraged (for the sake of clarity) to state the letter, then an example (to separate the Ms from the Ns, the Ds from the Ts) a la "P as in Pickle". But me, I can't the easy way out... it was always "P as in Psychology" or "M as in Mnemonic". Periodically I'd get a chuckle out of a customer, but more often, my mind conjured up images of people with blank stares holding the receiver up to their addled heads.

Anyone like to add to my collection?
