Well at least it's not Garfield

I agree with everything you said, yet I still enjoy these comics. ¯\_(ツ)_/¯

I think he could've touched more weird things we humanoids do that do feel alien to us if we step aside and really think about them.

I think Nathan Pyle's work is hilarious. The Strange Planet stuff isn't for me, but the rest of it is.

Different folks different strokes. I don't think there's much to gain from analyzing why something may or may not make you laugh.

I feel the same way about pizzacakecomics. Not once has it made me laugh personally, but judging by upvotes a ton of people like it

I recommend you to actually do write jokes on your own, (simple) creativity like this can feel really great.
