I'm honestly not even sure this qualifies as a prank, but I can't think of a better word for it. At least we know Arsenal Fan TV isn't the only awful fan-run YouTube channel, I guess.
I don't speak French, so I'm not entirely sure why any of this is happening, but here's Arsene Wenger playing soccer tennis in a suit. This can't be easy. I tried to juggle on a futsal court last night and almost broke my leg, for goodness' sake.
