I'll wait till tomorrow with revealing the answers. I didn't know the story about the passport and the naked girl, although that sounds like fun. Senna was very meticulous with his briefcase. As Senna and Berger were flying over Monaco in a helicopter, Berger tossed Senna's briefcase out. Senna was very angry and got back at him by placing frogs into Berger's hotel room. Or so the story goes.
a) Pironi and Villeneuve fueled their helicopters up and hovered over Monaco until one would give up and land due to lack of fuel. Never heard who won. b) As discussed: Berger threw Senna's briefcase out of the helicopter over Monaco. Senna placed frogs in Berger's hotel room. c) Nannini did his first helicopter solo at a family party and crashed. He was tossed out of the helicopter and one rotor blade cut his lower arm off. The cut was clean enough so the surgeons managed to reattach it in the hospital. Talk about crashing a party....
