This has got to be the second weirdest place to read a book, the first weirdest place being in a Mobile Suit in Earth Orbit, as done by Zechs Merquise in Gundam Wing: Endless Waltz. ("Hello?! There's an invasion going on! Why are you reading a book in your cool mobile suit?!)
I think it's quite sweet, shows there ARE some men who don't mind soaking in the hot tub with their lover instead of just wanting to fuck in different places. :P
