Sculptors often express themselves in strange and mysterious ways, but most sculptors don't have their works on display in a public park.
Frogner Park in Oslo, Norway has chosen an odd assortment of statues to fill their park, 23 works that center around nude forms in weird poses doing who knows what to each other (nothing pornographic, I assure you) and often looking quite happy doing whatever it is they're doing.
BuzzFeed has a gallery showing off these enormous oddities, take a gander and i'm sure you'll be asking yourself the same thing I did- "Wait, what's going on here?"

The sculpture LisaL mentions, the girl on the reindeer (not deer), is from the nearby Vigeland museum, where copies of sculptures placed elsewhere in the kingdom is displayed, and is not found in the park.
An interesting piece of trivia is that the Frogner park was originally bought by the city of Oslo to be used as a graveyard, but was repurpoused as a public park because there was too much stone in the ground(!).
It's a symbol for them, like a national icon or something like that.
