Humans enjoy the weirdest things. The window in our current mini-house looks out over a "pool," which is basically a big bathtub that's always filled with water. And various humans, especially the small ones, go outside all day and jump into it and splash around!
I'll explore the tub in the bathroom every now and then, but only when it's not in use. (The residual water HAZ A FLAVR.) These humans outside actually submerge themselves in the pool water for hours at a time! I know--I've been watching them. Maybe it's different when your body's not covered in fur, but still. Wet! Uncomfortable! Inconvenient!
