[Tom]

  I know them all!

Some better than others, but I know them all!

[The Peepmaster]

We'll never get Roger to use all them in one weekend!

[Diamond Lil]

fell at the last fence..ziggurat?...desperate now for that to come up in a crossword next time I attempt the one in the 'Babylonian Times'

[Malc]

Well, I've been called almost all of them at some time or other.

Are we supposed to have heard them at some stage (yes) or should we know what they all mean? (yes, sort of).

[Tarquin Thunderthighs lll]

Heard of about two thirds, and knew the meaning of about half.

The rest I found rather recandite, if not orphic. Certainly acroamatic.

[Mince]

"recondite", Tarquin.

[Tarquin Thunderthighs lll]

I stand currected!
