hmmm...I myself stare at my door until I start to drool a little. not really sure why, maybe thats the only real time where I allow the functions of my brain to slow down.
other times, my dog meets me in the bathroom and i play with her (an actual dog, nothing dirty intended).
I don't really do anything on the toilet...I just get in and get out :P
Yea, I dont know why people do stuff on it snce its kinda akward, also I remember in my old school, the main reason people were getting new phones was they dropped theirs in the toliet.
well, I am usually on the toilet for 15-20 minutes or more, so I usually read, take a dump, shoot hoops with balls of toilet paper, and totally space out, daydream, and one time I almost fell asleep and I drooled on my leg. (It woke me up :P)
