We're totally not smart enough to understand everything about this Boing Boing post about brain activity and porn watching, though we do need to point out that the link between fishing videos and dirty movies is not as much of a stretch as some scientists might think. (Also, anyone know where we can pick up a gently used penile plethysmograph at a good price? Sounds like just the thing to make our weekly intern orientation programs here at Fleshbot Central a little more interesting.) (boingboing.net - thanks Tits)
