I don't think the point of this new trend of comic remixes is to point out that comics aren't funny. It's to take this pedestrian source material and with a few tweaks turn it into something really weird and good.
My only problem with it is that these internet trends get run into the ground.
I also find the Comics Curmudgeon's commentary on Curtis-- pardon the alliteration-- to be very funny. When he points out how Curtis and his little brother talk more like elderly jewish men than young black kids.
