I kinda like That 70's Show. Not as much anymore, but when it was on originally, I did used to watch it pretty much every week.

One character that would show up on occasion was Big Rhonda. She was supposed to be a big, kinda chunky gal that was a bit geeky, dated Fez...

She was pretty obviously played by an actress in padding, but it was always hard to figure out exactly what she looked like.

Well, I found out. Her name is Cynthia Lamontagne.
