As I look around at some kids today with their mohawk haircuts, I have to continually remind myself that these are not my kids.  Well, this is the Mohawk Valley, Ha!  Oh, read on.  I don't recall have crazy haircuts until I reached my teens, but Tan Chaoyun, mother of four boys in China, just gave all of her youngsters distinct Mohawks on top of their heads.  Hey, you can hardly blame her. Her six-year-old boys are identical quadruplets and she took the drastic step to help teachers and classmates tell them apart. So each boy now has a number (1 – 4) made of hair on the top of his head. Tan says, "My sons are identical, even to me! The only difference between them is the shape of their eyelids.  I could only tell the difference between them by having different ankle tags on them before they turned 18 months old.  Even now, their father can't tell which one is which. Sometimes he punishes the second one for something the third one has done."
