It's the only way to be sure.
Incidentally, I bet you didn't know that I know the guy who (very sporadically) does Alien Loves Predator. It's kind of hilarious how I learned this. A bunch of us were having drinks, and he said, "Oh, you have a webcomic? Neat, me too!" "Yeah? What's yours called?" "Alien Loves Predator." "OH SHIT YOU'RE THE ALIEN LOVES PREDATOR GUY?"
Bernie claims that no one had ever reacted to that information quite as enthusiastically, but I think he might just be used to downplaying himself because he's had the table next to Kate Beaton's at comic conventions.
