Razor blades: Those things are expensive and I hate having to buy them. Who wouldn't be happy to find some Mach 4s in their breakfast? I see no reason why this wouldn't also work with Halloween candy.
Condoms: Also expensive, and I always seem to run out at the wrong time. Wouldn't it be great if I could say, "relax, baby, I got a box of Lucky Charms in the kitchen"? The condoms wouldn't even need to be wrapped; the crumbs might be uncomfortable at first, but it will be worth it when I can go around telling the ladies that I'm "magically delicious."
Immodium AD: I love cereal but I'm lactose intolerant. Now we're selling the solution with the problem, like peanut butter and jelly in the same jar.
An AOL CD: They're nearly impossible to find, and I've been looking EVERYWHERE.
Rolling papers: Uh" no particular reason, but I'm thinking these would come in handy when I'm in the mood for cereal.
