If you have a well-shaped skull, shave your head, plane it with a sander and polish it to a high sheen. And so on for other parts of the body. You can work the rest out for yourselves, for Christ's sake. And hide your defects. Swathe your entire head in bandages if you really feel uncomfortable with your looks.
Women love mystery.
Smell flowers a lot. Cry when you see tramps or ugly buildings. Cry when you hurt yourself. Don't do spastic impressions or light your farts when you've had a few. If the girl you fancy seems subdued or moody, ask her in a sensitive voice if she's on her period.
