He really can keep a straight face, and when it's his lines time "He Delivers"

I've only seen Seasons 4 & 5 so far ...

And the writers gave him great lines ! He steals the scene many times !!

Even at times Marjorie Lord can't help but smile when Rusty is ON

very sad on his sad end of life, but I think he did a great job opposite the very dominate Danny Thomas

Yes, he was really good. Sort of an earlier version of Danny Bonaduce.

Yes, he DOES remind me of Danny Bonaduce too.

Yes, they wrote really well for him. I never thought of the Danny Bonaduce comparison,but it's perfect.
