Was extremely proud of his grandfather, actor/comedian Pedro Gonzalez Gonzalez, who was, for the most part, a victim of Latino stereotypes in 1950s/1960s John Wayne westerns and sitcoms. As a tribute, Clifton changed his professional name to Clifton Gonzalez-Gonzalez in 1990, claiming that he was tired of people not knowing his grandfather or appreciating the significance of his ordeal. He reverted back to the name of Collins in 2000 after his father passed away.
