Here's an answer I doubt anyone else could give: I was trying to impress a hot guy.
Story was I was sat in my Uni library last year and this insanely cute dude was next to me, watching what to me, at the time, looked like some stupid slideshow with the worst background ever. But, me being the clueless moron I am, I thought if I was interested in the same thing as him, and watched it, he'd suddenly magically notice me. So I managed to identify the web address, which led me to Yahtzee...and thus was born a relationship that will last a lifetime. Or until he stops. Or until I lose interest.
