Two-time Formula One world champion Sebastian Vettel appeared on the Late Show with David Letterman on Tuesday, managing to use a swearword and talk about his testicles in the ten-minute interview.
Vettel, who came in fourth in the Canadian Grand Prix after starting on pole on Sunday, got into a technical discussion with David Letterman. The host asked question after complicated question, prompting Vettel to say: "Now you're making it really complicated. People here have no f**king idea what you're talking about."
Letterman, who owns an Indy car team, kept talking about the Indianapolis 500, which he branded "the greatest race in the world". He also asked the German about an F1 circuit currently being built in New Jersey.
"It looks very quick... you need some big balls, I think," Vettel said of the track.
