Berger later recounted further events before the 1990 Australian Grand Prix. "After dinner, we started to throw people in the swimming pool, all dressed. As I was good at defending myself, I escaped from the bath, but many people got wet. Senna ran away to avoid us from getting him, however, later, I went to his room and he awkwardly threw a glass of water at me. For a Tyrolean, that was nothing, but it did mean that the game was now on. With a hose, we improvised an extension to the fire extinguisher and we put it under his room door at three in the morning. We invited some people to watch and when we pushed the lever, Senna flew out of the window like a rocket. It looked like a bomb had exploded inside the room. The confusion woke many people up, who started to scream at Senna for making so much noise. He was terribly embarrassed."
