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.
In "The Finale, Part 2," Helen and Morty were seen attending the trial of Jerry Seinfeld, Elaine Benes, George Costanza, and Cosmo Kramer in Latham County. After the four were found guilty, Helen is shown crying over this as Morty comforts her.
