Helen Seinfeld, played by Liz Sheridan, is a fictional character on Seinfeld. She is Jerry Seinfeld's mother. Her husband—Jerry's father—is Morty Seinfeld. She thinks Jerry is perfect. Helen's catchphrase in the series is her rhetorical question about Jerry, "How could anyone not like him?" According to Jerry, Helen has never once set foot in a natural body of water. She is a retiree who lives in Florida. Anytime Jerry's father is on the phone Helen is always talking with him on the same line.
