Help Identifying this Cartoon

I didn’t see the entire animated short but there was a cowboy type figure who was riding in horse and carriage and seemed to be heading toward a grave yard. The music that was playing was “I’m a happy boy…I’m a happy boy…”

The animation was definitely computer based --and that’s all I can offer.

I’d like to think I didn’t merely hallucinate this whole episode but I can find nothing through the cursory internet search.

Any help from out there?

Anyone?

I bet you are remembering this (the portion starting at 1:30).

Wow. Thanks pink, that’s definitely it.

So I guess I didn’t hallucinate it but the toon sure has a trippy quality about it.

Thanks for the quick reply. Man I love this place.
