“My mom hates me,” comedian Kabir Singh tells a rapt audience at a Dry Bar comedy show in Provo, Utah. “I have two sisters. One’s a lawyer, the other’s a doctor — and I’m this.” Quips like this have helped propel the 37-year-old Fremont comic to appearances on popular shows — including “Gabriel Iglesias Presents Stand-Up Revolution” on Comedy Central, “Dry Bar Comedy” on YouTube and “Family Guy” on Fox — a first-place win at the San Francisco International Comedy Competition and, now, a performance on NBC-TV competition series “America’s Got Talent,” coming up June 15.
