In The Swell we see a legion of vampy kittens who penetrate human bodies through mouths, suck them dry and then burst out ot cavity chests. I mean - how disturbing it is?
Isn't that what happened in the first three episodes of Angel? However, references to manga when everyone does not read it does not make for fun references, I'm sure. Then again, it worked on South Park...maybe it just doesn't translate well (the reference I mean) in comic books?
