Seventeen-time Grand Slam champion Roger Federer is immensely talented, but not at delivering a piece to camera.
The world number two was simply asked to read a few lines off the autocue before signing the camera lens as an intro for TV show Trans World Sport, but it went a bit wrong.
Federer reeled off the script with consummate ease, but things swiftly unravelled for the Swiss star as he left the cap on his pen as he attempted in vain to sign his autograph on the lens.
It was a cute gaffe from the star, but thankfully there was a second take which he nailed before signing off. Well done, Roger!
