To deal with the problem of having to tell one of her quadruplets apart from the others, a mother in China came up with a novel approach: She shaved the numbers one through four on their heads.

Though Tan Chaoyun says she was prompted by concerns from his six-year-old sons' school that teachers would be unable to tell which was which, she admitted that both she and the boys' father were unable to tell them apart at times.

"Their father [has trouble] telling the differences among them," she told the local media. "Sometimes he would punish the second one for the third one's mistake."

The numerical haircuts seem to be a step up (or down, depending on your take) from the ankle tags Tan used to rely on when they were younger.
