I'm sure I will commit a faux pas doing this, but, there is a really cool post over at B & B called "Barber Trick" in the General section by "icemncmth". Since I so rarely look into the General area I thought I'd mention it.

For those not inclined to look, it involves him watching a barber with a new client and running a cotton ball over his face to determine the grain. Its a nice quick read though. Two thumbs up, as they say.
