Dinty, those guys are North Germans all right! Even (!) we aren't above making a little money when we get the chance (I never seem to do ...), and even (!) we aren't above a liking of low humour. Who is? It is just that there are different kinds of low humour. Me, I love dirty jokes but I hate toilet jokes. Must be why I could never understand other people's fascination with Monty Python.
So don't brood on it. You're as welcome to your tastes as I want to be to mine, and I'm sure if we got together we'd find a few common ones. It's only human. :-) - Susanne
