[pen] My recollection of Dutch humour was that they gave you very fair warning of an imminent joke, often some days in advance, allowing one to take cover. Is it still like that?

Our Finnish friends, who owned an underpowered 2CV, used to refer to it as the 'un cheval'.

[Superman] I get the 'flea' moniker and the coffee-pot (I'm thinking of a Bialetti stove-top espresso maker - does that make me one of the 'liberal elite'?) but it does take time for objects to earn an affectionate nickname, doesn't it?
And as for slow-simmering Dutch jokes, I haven't actually noticed any, probably because I don't work with enough Dutch people for the technique to gain critical mass. They're not without a sense of humour, but because mine relies on wordplay (most often) then there's a gap that isn't often bridged.
