I read Camiggelt when I was in my teens (which is quite a while ago) and loved his writing a lot.
Anyway, nowaday you never find one book by him in a bookshop, all you want to read from him has to be acquired in the second hands bookshops.
Here's some more info about the expo.
He had a great feeling for oneliners, some of them can be found here.
What about this one :
"Geld maakt niet gelukkig, dat heeft het met armoe gemeen."
