Should be this one. Got it from channel4 website:
23:00 The Perfect Penis
The penis is the organ most central to a man's sense of self, and the quest for penile perfection has driven some men to extraordinary and dangerous lengths.
I hope that someone will record it for us non-UK...
I've got a similar thing but with a bigger girth difference.
6" at the base down to 5.1" below the head.. I really need to even it out.. On the other had it allows easier penetration :O :P
