Not enough dog buttholes.

When the GoPro strap-on camera first began making waves, it seemed its primary purpose was to be attached to snowboarders and other daredevils (like, say, some skydivers watching two planes collide mid-air). Then seagulls and eagles started picking them up, people dropped them out of planes and into pig pens, and finally we realized that the best things they do are to let us see the world in ways we can't (or at least can't do safely).
