What's the porpoise of that then?

'Phoned the insurance company today. By the time I got through, I'd completely forgotten what I wanted. The call was answered by a robot, saying "this call may be recorded for training porpoises". What on earth are they training porpoises to do? Of course, then the obligatory Greensleaves, this time played by Rolf Harris on what I can only describe as a budget-version stylophone which sounded like Rolf had injured his hand in a freak wobble-board accident.

Phrase of the day - ipsissima verba - sounds great, doesn't it?
..... means "the precise words".
Nothing to do with anything, but while I was waiting on the phone I had nothing better to do than flick through the old Concise Oxford.
