John Varvatos's clothes are the only ones Howard will wear (so long as they're black of course). So Howard welcomed his favorite designer on the show to talk about how he made it in the fashion industry, and how he feels about being pretty much the only heterosexual male in it.
Howard told the designer that he actually assumed John was gay when he first met him: "I thought he was just a really nice gay guy!"
John, however, has been married twice and has 3 children, and assured Howard that he never had to blow anyone for a job. So just how did this straight guy make it without a queer eye then? We couldn't tell you.
