you know one, you know 'em all

A woman has twins, and gives them up for adoption. One of them goes to a family in Egypt and is named "Amal." The other goes to a family in Spain; they name him "Juan." Years later Juan sends a picture of himself to his Mom. Upon receiving the picture, she tells her husband she wishes she also had a picture of Amal. Her husband responds, "But they are twins -- if you've seen Juan, you've seen Amal."
