I think it really was just Ives, not the whole franchise. (I've been dealing with our Property Management Grinches and I got a little I HATE EVERYTHING, I think)
I believe you're talking about the awesome Fred Astaire puppet mailman guy they had in one. Actually liked that, too. :)
I retract my previous statement and replace it with:
"But, man, I really don't like the Burl Ives music in them. Mainly because I don't like Burl Ives."
