wait, i don't get what you are trying to say... if you get these jokes, and you don't think they are funny, are you really getting these jokes?
the fact that you said "someone punching santa was funny" makes me think you really don't get it... they are completely different type of humor
in fact, you can't really say they are "jokes" either, the types of humor are called "tsukkomi" and "boke," which are "passive humor" rather than active ones like you saw in paniponi dash (yes, it's different than paniponi dash... not all 4koma are the same)... best example i can give you is kyon in haruhi who's pretty much the greatest tsukkomi in any anime i've seen lol
"tsukkomi" and "boke" are really not "funny" but rather "humorous" in that if people do it well in real life conversation they are regarded as witty and fun, but very rarely do they provoke burst out laughs like "jokes" do
but again, there's no way i can make you understand if you don't really get it by experience (or at least speak a little japanese), i'm just trying explain it well enough to you so you realize there IS another side of this globe and people don't have to be and act the american way
