I don't think I ever watched Hardcastle & McCormick but I was a big fan of Scarecrow and Mrs King and Riptide when I was a kid. I remember watching those shows with my mom, who liked them a lot, too.

And they live together.

And don't they actually sleep in the same room, too? That is, for Nick and Cody, IIRC? Living on a boat is just awesome, there're such little space :-)
