"Somebody ask for a kid?"
Exactly.
Robbie Rist was probably the first incarnation of the practice as “Cousin Oliver”.
However, none was more aggregious than the additon of baby Keaton to “Family Ties”. The following season, the kid was FIVE and talking. The show died a quick death and the kid who played the remarkably-aged baby is now a casualty of Hollywood Kids.
I was just thinking that this turn of events would be about as successful as Galactica: 1980, and up pops a photo of Robbie Rist! That's gotta be a harbinger of Hollywood doom.
