There were actually two kids in those commercials.
* The boy was played by Gene Gianfala. He sadly passed away in 2003 at the age of 46 from a heart attack.
* The girl was played by Erin Murphy. She's still alive and active, and she's best known for her role as Tabitha in the popular TV show "Bewitched." You can find her on social media, and she has even appeared on some celebrity reality shows in recent years.
Although the commercials were from 1973, they remain popular and recognizable to this day.
