The Ropers had one of the most wackest opening theme's. Laughing my head off!:happyface

Down To Earth had a wacky opening theme. :D

Lavern & Shirley

I can't remember the name of the show, but it showed the son of Bob of Bob and Ray (Chris Elliot)riding a bike he was 5 times too big for and in the background you could hear the singer singing: "Stand in the place that you live. Think about direction wonder why you haven't before."

The first season intro to Growing Pains is kinda weird in a way, partly because they're ripping off the Cheers intro to an extent.

The Monkees - The opening was wacky in its own fun way.
