Why does Brussels smell like urine?

Katia took me out to the streets of Brussels for a lovely evening.  A highlight in Brussels is
the peeing boy.  I should Google why there is a peeing boy, but I've told that there is a peeing girl and a peeing dog.  And this is in the tourist area.
What happens when you travel to the outskirts of Brussels?  Is there a pooing boy?
     Anyway,  a beautiful city.  Worth a visit.  On my way to Nancy, France tonight.  I may wear my fancy pants in Nancy, France.  (I am beginning to sound like my mother in law)
