Before D&D, my Saturday mornings consisted of a wonderful, if twisted, children's show called The Hilarious House of Frightenstein.
This show was created in the early 1970s at CHCH TV in Hamilton, Ontario. Basically, right in my backyard.
If you were a Canadian child in the late 70s or early 80s you likely remember this show.
The majority of the characters in the show were voiced by Canadian actor Billy Van - he was quite something and this show speaks to his range and talent.
Here's a 10 minute episode. Having said that, I always like the wolfman radio DJ. So I cut right to his bit in the second video. You can find more on youtube.
Some of it was pretty trippy for kids.
