At least, I think it was the '70s since I was so young when I watched it. It was superheros living together but it wasn’t superhero-y, it was funny. There was a baby who flung his bottle and a crazy one, Birdman I think, but not the Birdman from a more recent cartoon. This one was a cuckoo bird man. He used to say, “Coo Coo! Coo Coo”
There may have been one or two others. Does this ring a bell with anyone?
I loved this and still have a copy on VHS…though nothing to play it on. 
Oh man, the memories. Dig that hyper-intense classic Ralph Bakshi artistry on the intro, and the propulsive music!
That was fast!
Only one season in '66? I must have seen it on reruns.
Yes, it would have been early to mid 70s that I saw it, syndicated on Dallas TV.
Holy cow! I remember that, too, though I probably haven’t thought about it in 30 years.
Well now. They may have over-emphasised the American iconography there a tad.
