His first role was in Brady Bunch?

I don't know how many times I have seen this Brady Bunch episode, but this time I wasn't paying attention, but heard a voice that sounded familiar.

He was in the play that Cindy had the starring part. Imagine that.

You didn't say who.

Oh, Chris II.

Chris 2? I don't remember seeing him in the Brady Bunch.
