With my friends it is customary to buy silly things for each other's birthday. You go to one of them shops where they have all sorts of nick nackeries. You buy an ugly reproduction of "the boy with the tear" or the "gypsy girl". Or you buy old vinyl records of "Henk Wijngaard" or "Racey".
When you really want to get "even with your friends you give these things back at their own birthday and you act surprised.
That is our kind of fun. This year I got Heino, Demis Roussos and Nana Mouskouri...
About ten years ago I got a very silly LP with a very silly cover with four people wearing colourful clothes that seemed to be inspired by fairytales.
It was a record by the band called The Fool. I had never heard of that bunch of hippies and the music was really awful. Lots of fun at the party!
I kept the record for a few years and at a certain point I needed and old vinyl record for another birthday. So I took that ugly record by the silly band The Fool and sprayed the vinyl gold and made a personalised cover and glued it on top of the cover.
A few years later I found out this record is a collectors item. People pay top dollar for that record...
