Manneken Pis, Belgium
Yes, the name of this statue in Brussels pretty much translates to "Little Man Pee." No, we don't know why tourists flock to look at a statue of a naked child peeing. If you insist on going, time your visit for when the statue has been dressed up by a city employee—you’ll feel a little less like a creep. (Or come during one of the occasions when the fountain's water is replaced with a keg of beer, so you can at least get a free drink out of it.)
Instead: Visit the Zinneke Pis, a lesser-known sculpture in Brussels of a dog doing the same thing as the Manneken Pis. At least that one is cuter.
