These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Santa Claus Is Comin' to Town
Accidental Innuendo: to a modern audience, there are certain lines that can be misconstrued as meaning something else. This includes:
"I like babies"
"He will eat with us and sleep with us and drink warm cocoa with us"
"I'm a MAN now"
The entirety of "If you sit on my lap today..."
Alternate Character Interpretation: He may be the Burgermeister's #1 lackey and cause a lot of trouble for the heroes later on, but Grimsley is genuinely worried when the rope attached to Baby Claus' sleigh snaps. He tries to follow it into the blizzard before getting stuck in a snow drift.
Winter, powerful as he is, has a few stupid moments. How does he not see the obvious pile of sticks right under his feet in the beginning?
"Ooooh, she's Mrs. Claus!" Yeah, we never saw that coming.
"I knew it, I knew it, that's how he got his name!" Yeah, the fact that it is his (birth) name should have been a clue.
Values Dissonance: After two generations of increasingly extreme paranoia over children being sexually abused/molested/exploited, the song "If You Sit On My Lap Today" just doesn't sound as innocent now as it did back then. If Kris sang that today in Anytown, U.S.A, he'd either be chased down by an angry mob or beaten down cowboy-style before being forced to register as a sex offender for life. He 'charges' the kids one kiss for every toy he gives them! The sequence featuring this song has been edited in most modern-day airings (ABC Family, at least, has restored this and the "My World is Beginning Today" sequence, also cut from most modern-day airings for the reasons listed below, since 2010).
