"The Year without a Santa Claus" - 1974 is one of the most beloved Rankin-Bass holiday stop motion animation cartoons. Perhaps it's not quite as ubiquitous as "Rudolph the Red Nosed Reindeer" - 1964, but it's characters are definitely more popular- Namely, the Miser Brothers.
Afterall, Yukon Cornelius and that elf who wants to be a dentist don't have people making awkward tribute videos of them, do they?
I'm not sure which one I like better. The dour pre-teen Snow Miser has better special effects, but the Heat Miser Dad has way better dance moves!
