Before he died from leukemia, he enjoyed the last year of his life by surfing on trains. Included Germany's fastest Highspeed train ICE with a top speed of 330 km/h(!) No one did that before. Never to be forgotten R.I.P

In fact he didn't die, that was a spoof. But he was caught and prosecuted. I think he got off because he'd bought a ticket. But he was lucky; you can get up to 10 years for that sort of thing. And he has a 4 year old daughter, so his antics are at the very least irresponsible.
