Santa should've told off the other reindeer for making fun of Rudolph. After all, he knows who's been naughty or nice, amirite?

Reindeer don't get presents. What difference would it make?

"Oh, wow. We can't pull your sleigh this year because we bullied Rudolph? That's a pretty convenient excuse considering you've been picking the same reindeer for the past century. Just sayin'."
