Whole show sometimes seemed to revolve around rotary telephones or various novelty communication devices. When not revolving around unicycles or other things on wheels, like bathtubs. Or bicycle-powered mobile harpsichords or something.
Normally I don’t like physical comedy and slapstick, so I’m trying to figure out why I like this. I think it might hinge on Mike Nesmith’s face and his slightly edgy deadpan. It reminds you that the show is parody of many things, including its own slapstick.
