I'm not sure that that's actually a genuine photo-I think that may be a clever edit of another picture,which is a trick PF has employed before.Looks to me like the one where Fed held up the sign saying he was supporting the squash bid for the Olympics,though not really sure about that one.
I could be totally wrong though of course,and if I am then all credit to Fed for playing along with the joke.
Could be, Dani. Here's a shot from the Squash Back The Bid promo. Different over-shirt and colour of t-shirt, but anything is possible with photoshop.
And if it is a fake by PF.. well, that's even more hilarious, innit?
