I like 'ice ice baby'.
Once me & a mate were in a bar and they had a jukebox. 4 songs for the guilder (yes, it was a long time ago, before we got the Euro), so me and my mate decided to spend 25 guilders and programmed 'ice ice baby' 100 times and left. Few hours later we go back to that bar, we could hear the bassline outside and as soon as we stepped inside the barkeeper and the few remaining customers started to yell at us, we weren't welcome anymore

Most fun I had for 25 guilders
