May I suggest the following - stolen of course from somewhere else.
Pass the buck quiz - I start off with a nasty question and the poor sucker who get's it right has to pose a new question and so on. It's been going foe two months somewhere else and one doesn't have to be a "progmaster" to take part as most of us knows something that we others do not know.
Just to give an example I have found the following question:
In the 'Old Medley' from The Way We Walks (Volume Two: The Longs) Genesis play many fragments from their classic songs. In the cover book of the CD's they print only five of them - Dance On A Volcano, Lamb Lies Down On Broadway, The Musical Box, Firth Of Fifth and I Know What I like...
Do you believe me If I tell you there are more 5 songs in the Medley?
...And they are?
and off we go..........
