I voted for Sting, but I feel compelled to point out that I once wee'd on Mick Hucknall's shoes.
He'd been poncing about doing the "I'm a big star" thing in a pub I used to frequent (York Arms) and I was irritated, so when I noticed him at the next urinal I turned towards him and said 'Hey you're Mick Hucknall aren't you?" while continuing to piss and aiming vaguely in the shoes, lower leg area.
He got really annoyed and stomped off smelling of wee.
