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.
