I remember reading this one around the time the Berlin Wall came down...

An extremely rich and famous German sports star was carving up the roads one afternoon in a brand new Porsche. Passing on the right, speeding everywhere, he takes a blind corner at speed and plows into the back of a Trabant, sending them both spiraling into a ditch. Both cars are demolished. The sports star hops out of the twisted wreckage of his Porsche, to see an elderly man climbing out of the Trabant with a jubilant smile on his face. The sports star asks the gentleman if he’s okay, if he’s in shock. The gentleman raises his arms and says “No! This is fantastic! Let’s celebrate! We’re both alive!” He opens what’s left of his Trabant’s door to see a box of Cuban cigars. “What a miracle! Such an impact, and my treasured cigars are okay! Let’s light them and celebrate our good luck!” So the sports star and the gentleman light up, and smoke their cigars. The gentleman looks back inside, and sees his vintage bottle of Scotch and two glasses, and pulls them out. “A toast to us! Such a horrific accident and we made it through without a scratch!” He pours two very tall glasses of Scotch, and hands one to the sports star. They clink their glasses, and the sports star downs his. He looks at the gentleman, standing there with a still-full glass. “Aren’t you having any?” he asks the gentleman. “Oh no, not until the police give you a breathalyzer.”
