Yeah really it's obsessed people ike you who ruin it for other people. Twilight sucks and I believe we all have our own damn opinions so back off, this joke was hilarious. If you don't like this, then why the hell comment it? Back off. :]
I may not be a Twilight fan, but if you look at the other comments on this comic, you'll see plenty of people who are fans found it funny, even put it in Twilight fanart groups, and that's because they can take a joke.
Would I like it if a mutant child lasered my head off? Of course not. I wouldn't want to get eaten by a T Rex while I was on the toilet either, but that was HILARIOUS in Jurassic Park. Nobody wants actual snakes on actual planes, but the movie Snakes on a Plane? FUNNY! Edward and Bella sparkling in a romantic field? Not funny. Four panels of people being polite to each other? Not funny. See where I'm going with this?
But if you hate my comic (and hey, free country) then you'll really hate what it's based on, which is this movie here: [link]
The point is, you need to get wise to the fact that people are going to be making fun of stuff you like you're whole life. Haven't you ever watched Saturday Night Live? The Simpsons? A beer commercial? You can choose to see the humor in your own fandom, or you can choose to get angry over every little thing, but that second one is really going to drain you. Because at the end of the day, it's just a joke. Get over it.
