I suspect it was Sooty and Sweep.Google if you have never heard of them.
I bet it's something dangerously Welsh, like Rob Brydon.
Oh, Rob's nose is red. That happens a lot over here as well.
I think it was sesame street.
Felix the cat
Kukla, Fran and Ollie, Howdy Doody, and Captain Kangaroo - I'm not sure which was first, but I think it may have been Kukla, Fran and Ollie.
My brother and I watched that one too!
Howdy Doody Show ... it came on the air in 1947, the year I was born, and stayed on all the way through the 50's.
The Little Rascals on Saturday but we couldn't have the sound up - it would wake up my mother.
Ed Edd n Eddy, back in 2000 when I didn't know English and I just watched cartoon network without understanding anything. Thankfully my parents set me up on English courses and a few years later there were no words I didn't understand and if I didn't it meant I learned a new word.
Howdy Doody and Saturday morning cartoons (most are banned today!).
