The "Who's Your Daddy" recreational 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. For example, the test helped a 44-year-old Harlem man find his long lost 20-year-old daughter.
Rosenthal maintained that his credentials are legitimate and that his business is legal. In fact, he said he believes he is providing an essential service.
As you might imagine, wherever Rosenthal's truck goes it attracts attention. Reactions range from people saying 'How could he?' to others who saying 'Why didn't I think of that?' Rosenthal said he takes it all in stride.
The DNA tests, which cost between $299 and $575, require a simple cheek swab from each participant. Results are available in a couple of days.
