I am trying to find anything about a stop motion sketch I saw many many years ago-
It was stop motion but used Barbie knock offs, none of the dolls are Mattel, and had a very soap opera type story line. The particular part I remember had the husband of a married couple getting involved with bank robbers because his wife was pregnant. The baby would end up being an impossibly large out of scale baby doll. The title was something like "Ever expaning world" that would make sense with dolls.
It can't have been made before 1990 because one of the bank robbers was a NKOTB doll. I don't think it was on much after.
I think it was part of a sketch comedy show or edited together comedy clips. If it was on cable it would have been Nickelodeon, could also have been early Fox or syndicated to the Los Angeles area. It wasn't a little kids show.
It's almost easier to say what it wasn't.
