Funny Toilet sign

Yesterday I was in the renowned Schnitzelei in the western district of Berlin Charlottenburg. This place serves innovative alpine german food and you have to try it if you happen to visit Berlin for a couple of days. I saw something super funny there that catched my eye, a toilet sign with "Pipiweg" written on it.

You can see it on the last pic, hahah how I laughed as I saw it!!
