Everyone with a smartphone uses it as bathroom entertainment, right?
I’ve really taken to the IRB Laws app and quizzing myself [instead of watching Starcraft. what? Who said that?] It’s pretty effective bathroom entertainment! Also good for time killing in general – if you’re waiting for the movie to begin at the midnight premiere of the Hobbit for instance. You can take the quick 10 question “open book” quiz and browse the laws that you’re unsure about or unfamiliar with! The only downside is it won’t tell you which Qs you get wrong so just a better reason to KEEP AT IT. And do it again!!
