NEW YORK (CBSNewYork) — It is a sign of the times — getting a quick DNA test is now as easy as walking up to a truck. The “Who’s Your Daddy” recreation vehicle is selling DNA tests, mostly to fathers who suspect their children may not actually be theirs. “They flag us down, they pull us over, they talk to us,” owner and operator Jared Rosenthal said Wednesday. “Sometimes because of the nature of the services they want to be a little more discreet about it, but they do come or they’ll call the number.” In this business, Rosenthal said he deals with all kinds of crazy situations all day, every day. “We have people that want to get the specimen from their spouse without them knowing about it,” Rosenthal said. “We deal with a lot of drama. It’s constant drama.” There have been instances where men have walked in with a baby to give DNA samples, only to find out later they’re not related.
