@sweetsong256 In terms of children, they could probably adopt a child rather than.. you know what.. but if anyone were to fill in for them, I'd guess it be Dominic Field (Anthony's nephew) for Lachy and Clare for Emma. Sam probably wouldn't do it because A) He has child of his own. And B) He has since moved to his own show on Nick Jr. Brad also has his own business teaching kids and adults how to play piano. Also, nice reference to O really, O Reiley! My favorite gag besides "O no, O what?!".
