Tom Papa has learned a lot from hosting "The Marriage Ref" on NBC. For example: "Your wife doesn't necessarily like it when you flirt with a gorgeous movie star," Papa said about his wife, Cynthia's, reaction to his banter with Gwyneth Paltrow on a recent episode. Papa will be in town Thursday through Saturday, playing Helium Comedy Club (2031 Sansom). The North Jersey-raised Papa came up in New York and met Jerry Seinfeld on the stand-up circuit after Seinfeld's TV success. "We both got married at the same time. We would crack up on the road about stories. We've been exploring marriage comedically forever. When he came up with the idea for the show, he asked me to host," said Papa, joking that he told Seinfeld he had to check his schedule first before accepting. The success of the show is landing Papa in bigger rooms, which he says is his goal. "My whole reason for doing any movies or TV is to get more people out to my shows," Papa said. "This is such an exciting time in my life. I've been working so long - to have this kind of exposure and going right from Helium to New York for the upfronts, where NBC will announce our second season? It's a dream come true," Papa says. Tickets are still available online.
