George Clooney tells 'Entertainment Tonight Canada' he once pranked a friend for six years. "I got a painting out of the garbage that someone was throwing away, it was on the side of the road, I picked it up and I took it home and I signed my name to it. And my friend Richard Kind who was on 'Spin City', big Richard Kind - on his 40th birthday, [I gave him] this huge horrible painting of this naked woman, terrible painting. I said, 'I've done a lot of paintings, but this is the first one my art teacher is really proud of.' And he had to hang it, I was best man at his wedding, he had to hang it on the wall of his apartment. I left it for about six years before I told him."
