The joke on Santa Claus is Coming Christmas Tee is easy to understand, and that is a big part of why it works. It fits really well with Christmas, but you do not have to be obsessed with that stuff to enjoy the joke.
This would be easy to give as a gift for gift exchanges, holiday events, or any random day when you want to make someone laugh. If novelty t shirts are your thing, this one has a simple joke that is easy to wear. The whole point is to get a laugh, and the shirt does that without making things complicated.
