Yukon: You eat what you like, I'll eat what I like!
Plus the "I thought you said you wanted X" Running Gag.
"I'm cute! I'm cute! She said I'm CUUUUUUTTTTEEE!!!"
The sexism, which we can look and laugh at.
"Yes, they were very sad at the loss of their friend, but they knew that the best thing they could do was get the women back to town."
"No! This is MAN'S work!"
After Yukon comes back alive with the now-redeemed Bumble, he gives us this unforgettable line.
Didn't I ever tell you about Bumbles. Bumbles bounce!
When Yukon offers to give Rudolph and Hermey a ride, he yells "Mush!" at his dogs over and over. When they don't respond, he says "Like this!" and begins pulling the sled himself. What do the dogs do? Leap in the back of the sled and enjoy the free ride their master is giving them.
Then there is the fact that the breeds of sled dog that Yukon owns include a Dachshund, a young St. Bernard, a Schnauzer, a Cocker Spaniel, and a Poodle.
After the 'We Are Santa's Elves' number, Santa quickly says, "Needs work" and ducks out. After Mrs. Claus reassures the elves, the head elf whirls on them.
The fact that the Head Elf has this deliciously over-the-top sweet voice when talking to Santa, but as soon as he's gone...
Head Elf: That sounded terrible! The tenor section was weak!
Might be horrible, but during the musical number, an elf will sometimes smack around another elf. It makes this troper giggle a little seeing that moment.
