Manneken Pis

What is the deal with the statue of the little boy pissing? I kept wondering why myself and a few hundred others were there. Posing, taking pictures, making pee pee jokes, getting fleeced by the waffle stands...because one person a hundred years ago decided it would be worth seeing and everyone just followed suit? There are hundreds of beautifully carved statues within walking distance of this sculpture - that's completely covered up! It boggles the mind, but hey, you should go and pose for a picture, maybe even buy a waffle ;)
