In a video shared by popular Swiss chocolate manufacturer Lindt, 17-time Grand Slam champion Roger Federer makes a Skype video call to American World Cup alpine ski racer Lindsey Vonn. The video that lasted nearly three minutes shows Federer challenging Vonn for a game at a glacier mountain.

According to The Local, the video is part of a promotion for Lindt Chocolate, which opens a new store at the Jungfraujoch. Federer and Vonn played tennis at the top of the Jungfrau Railway, 3,454 metres above sea level on July 17 for a Lindt & Sprüngli chocolate shop at the Bernese Oberland station.

Federer is reportedly "amazed" how the Zurich-based chocolate manufacturer comes up with great ideas to promote their products. "Today on the Jungfraujoch was a real highlight for me," said Federer in a statement.

Lindt & Sprüngli's chief executive officer and chairman Ernst Tanner said that the new advertising targets to promote Lindt chocolate to tourists from all over the globe. "With the themed chocolate shop at the Jungfraujoch, we have positioned our brand to a lofty height," said Mr. Tanner. "Our aim is to introduce tourists from abroad to our Lindt chocolate up there," he added.

Vonn's dream of playing tennis with Federer finally came true. In 2013, Vonn tweeted about how she wanted to play tennis with the third-ranked tennis athlete.

If you could watch me play any other athlete in any other sport (other than our own sport), what sport and what athlete? #AskedRF

Federer became Lindt & Sprüngli's global brand ambassador in 2009. It was the first time in more than 165 years of the company's history that a famous personality has been signed as the ambassador.
