Twenty-one-month-old conjoined Egyptian twin Mohamed Ibrahim cries for attention while his brother Ahmed tries to take a nap at their apartment in Dallas, Texas on March 4, 2003. The boys, born joined at the head, have never had similar habits or tastes. They rarely sleep, eat or even cry at the same time. Even their personalities differ: Mohamed is usually more rowdy than his laid-back brother. Photography by Mei-Chun Jau/The Dallas Morning News. © Mei-Chun Jau
