Why are messy foods served at game parties?

Why do people bring/serve messy foods at game parties? I don't greasy, nasty hands all over my controllers and playing cards! Barbecue, pizza, pudding-based desserts; how am I supposed to eat these while I play games!?!?!? This all begs the question, what foods ARE good for gaming parties? Personally, I like cookies, pretzels and dips, dare I say even fruits and veggies, and most importantly, my wife's delicious won-ton ranch stars! Basically, if it can function in a bowl and be eaten (appropriately) with your hands, it's probably a decent game party food. And don't even get me STARTED on good party DRINKS! Daily Commute #11
