My guess is that most of the creativity involved claiming to be "Hispanic". Hispanics are a cultural group and not a racial group. As such, unlike Native Americans who are actually enrolled tribal members, there are not a lot of rules with being Hispanic. Hispanic physical features can vary- especially in the Carribean and encompass people with European, African to Asian features. Likewise, though most Hispanics have Spanish last names, it is not required. Zimmerman of the Trayvon Martin shooting and infamy is Hispanic and has a German last name. Other Hispanics can have Italian or eastern European last names (common in Argentina ala Pope Benedict) or on occasion, have Chinese last names. Then factor in that there are millions of Hispanics who don't speak Spanish. In short, if somebody says they are Hispanic, it is almost impossible to prove they are not with out going deeply into family origins.
