Video: Roger Federer in William Tell serve trick
Roger Federer, the six-times Wimbledon champion, astounded crew members at a photo shoot with a trick shot in which he knocked a drink bottle off a man's head with his serve.
The trick was similar to the legend of William Tell, the Swiss folk hero who was said to have shot an apple off his son's head with a crossbow bolt.
A short film uploaded to the video-sharing website YouTube shows the Swiss tennis number one replicate his countryman's trick by twice serving a tennis ball directly onto a metal bottle placed on a man's head.
The start of the video, filmed during a Gillette and British Skin Foundation photo shoot, shows the World Number Two apparently discussing a recent match with a crew member.
To prove a point about the accuracy of his serve, Federer challenges the man to stand with the bottle on his head before crashing two pinpoint serves directly onto it, sending it flying while leaving the man unharmed.
After successfully repeating the trick, he remarks: "What's next? That was good, right?"
The video, uploaded on Monday, has already attracted more than 50,000 views but has provoked debate as to whether it is genuine or not.
One viewer commented: "all the people who think this is real obviously have never played tennis let alone serving. it is not possible to have such precision especially when it's twice and there is a human involved. this is FAKE!"
Another remarked: "You really think this is fake? Yes the greatest player of all time can't hit a can from 20 feet? You guys are a joke. Of course its real."
