Margaret Cho marks her return to television with "The Cho Show," a new VH1 reality sitcom debuting on Aug. 21. Sent into a tailspin after the cancellation of her first small-screen adventure, ABC's "All-American Girl," in 1995, the 39-year-old spent the next decade touring the country with her raunchy stand-up act. She was lured back to the small screen with an executive-producer credit on "Cho" and the promise of more editorial control. Ms. Cho, whose parents -- and frequent comedy targets -- make extended cameos on her show, picked her favorite TV moms and dads.
