every time someone mention about dropping some valuable stuff in the toilet, i always thought about my Yu-Gi-Oh card 8 years ago(i was 10 years old), i dropped one very rare card in the toilet while #2 was still inside... i was still able to sell it for 5000 yen(i lived in Japan), about $50 in US currency, to the card shop(private owned shop where they sold bunch of game cards, used games, other stuff, where most kids hanged out) LOL ... ofcourse, i did not tell about that to the dealer anyway, i always tend to open AirCoaster Pro while im playing in the toilet..
Well, some of us rather read newspaper on the toilet, others like to play on their iPhones. And of course there are exceptions, as always.
Maybe in your own house. Certainly not anywhere else, as playing doodle jump without sound makes it much harder.
Btw, Libra balance LITE 2 is out: http://itunes.apple.com/us/app/libra-balance-lite-2/id342052249?mt=8. You should try out for free then let me know whether this game it's worth a session in the toilet at least.
