"We were arguing over half a million dollars, and I came up with the idea of us flicking a coin to decide," Dennis said in an in-depth interview with McLaren Mercedes website. "But Ayrton's English wasn't so good at the time, so there was a five-minute conversation about the details. I had to draw pictures on a piece of paper. I just wanted to find a way forward. So the coin was thrown into the air, spinning. It landed and it went off like a rocket! You could hear it rattling under the curtains, I pulled them back and I won the bet!"
That episode speaks volume about Dennis and Senna's playful mindsets. It also marked the beginning of a five-year relationship, sometimes marred by feuds and disagreements, but mostly made of joy. During his time at McLaren, Senna triumphed in 35 grand prix races.
