Rémi Gaillard is brilliant.
I came across him accidentally on Youtube, and I then spent several hours watching his pranks. You can find them by searching Youtube, or you can go to his web site.
He's French, and il ne donne une baise. He pranks anyone and everyone. He put on football strip and pretended to be part of the winning side, shaking hands with the president of France.
My favourite prank is very short and simple - the pigeon. I've watched this one minute clip several times, and I laugh out loud each time. Also especially look out for the snail, and volleyball (singing the Marsellaise; he seemed to be the only one on the team that knew the words, so the news camera focussed on him).
