When you're buying special bags just for slices of pizza...there's something wrong with loving pizza THAT much.  And notice the pic that VladTheHampaler linked to...that's my point.  Also, notice the size of the goddamned bag.  That's a brooklyn slice-sized bag.  Who the fuck gets pizza that big often enough to need special bags?  I love a lot of foods, but I use the exact same storage methods across ALL the food I own.  I have tupperware (well, a different brand, but you know what I mean) for some things, and ziploc bags (ordinary ones) for other things.  I don't have "steak bags" or "sushi bags" or "pizza bags" or "Ethiopian food bags" or anything like that.  I would bet you money that anyone who idolizes pizza enough to want special bags just for their pizza is fat, and eating too much pizza. It's also about context.  ThinkGeek's site caters to fats, such that niche items such as Star Trek bathing suits (because, let's face it...these are not going to sell by the millions to begin with) also come in plus sizes (chastity upon chastity).  Peruse their site sometime...and be prepared for an outbreak of Tourette's syndrome when you do.  It's a combination of beta orbiters, fats, and girls who don't rank above 6.
