Ruby on Rails became popular with teenagers partly because of "Why's Poignant Guide to..." (and I forget the exact name.) It was full of funny drawings, jokes, and memes.
Honestly, I couldn't make it past a few panels of this comic. It's a good idea, though.
I think the reason why Why's guide worked is that the content came first, and the jokes were more for comedic relief. Trying to make everything a cutesy analogy doesn't make it more accessible. Pacing is just as important.
So, yes, I (and I assume many others) benefit from the content. Of course that is not to say it is for everyone. Personally I don’t care much for learning from videos but know many people who much prefer them to text.
I doubt there is a single, universal style of learning medium that is optimal for most (let alone all) learners.
