When I was a kid, not only was I a "Buy the strategy guide" kid, but I was a "Read over the strategy guide of the game I'm playing all the time just because" kid

As a secondary fact, our GP when I was growing up had a really sharp sense of humour

Anyway these two facts coalesced one day when he looked at the Pokemon strategy guide I had sitting open on the examination bed next to me and then informed me very solemnly "You have Piloswinitis"
