Another thread reminded me of the Beatles cartoon show from the 60's. It's not the Beatles' fault. They had no part in its production. The show falls into the "So awful it's great" category. Most of it's on Youtube.
The Penny Lane episode's particularly weird:
If you want a chuckle--and to be completely weirded out--give it a look. Your jaw will hang open in utter disbelief. I particularly like the bit where the crazy fireman chases Paul out of the barbershop with an ax.
And those fake Beatles voices....Holy cow.
