Sure we all want our own private island, but Neatorama's favorite performance artist Antti Laitinen actually did something about it: back in 2008, he built himself a floating palm island that he rowed on the River Thames! The police, however, didn't seem to be too enthralled with the idea:
I rowed my palm island down the Thames with the aim of rowing through the centre of London. After a few kilometres of rowing the police pulled me over in front of MI5 and stopped my performance. They asked me if I knew what building I was beside and I said 'yes, that's along were I am going.' They didn't agree, and towed my island and me back up river.
Check it out on Antti's website.

The only reason he would get any hassle at all is if he didn't have the relevant registration for his boat. He did have that didn't he?
