A controlled-temperature swimming pool: warm in winter, cool in summer.

Yay!

*Jumps in*

*stands on side throwing peanuts at swimmers*

*Splashes water at people standing that's throwing in things*

*stands further back from side*

I reckon I can throw a peanut further than you can splash water 

Wanna try? *runs to get that super-configurable-hyper-mini-water-cannon of mine*

*blasts off to peanut-launching moon-base*

*shoots it down with my laser-like water beam*

*steers flaming wreckage down towards the swimming pool*

*Uses a pair of the portals from the game Portal and sends you to Mars*

Can't argue with portals...

But I'm still alive.

LOL! Didn't take long to get all sci-fi!

wants to play Marco Polo?

"Marco!"

getting out of the pool "Polo!"

...!?

*slams into the water, effectively draining it*
