If you can't find a hot chick who likes Amigas, you could always try one of these ideas:
Find a hot chick with at least half a brain in her head (almost as hard as finding a hot Amiga chick, but not quite as rare) and introduce her to your Amiga. If she's smart, she'll love it, and you'll soon have a hot Amiga chick.
Find a fat Amiga chick and kindly ask her to start working out and eating healthier food.
If all else fails, join more IRC channels and snare a live one online and get her shipped to you.
