What do you call a reindeer who's an excellent decorator?

Deer-ator

Why did my true love get me a gift receipt instead of the actual presents from 'The Twelve Days of Christmas'?

Because returning nine ladies dancing and ten lords a-leaping is a logistical nightmare.

Why did Santa's elves go on a team-building retreat at the North Pole?

To get to the root of their workflow and branch out into new collaborations!

Why do Christmas carolers always sound so insistent?

Because they won't leave until they get their figgy pudding!
