1. Insomnia Cookies
What you’re providing: You’re not bringing anything -- the rapidly expanding company is delivering it to you, at 2am. As for how many, you can customize the type and number, or get one of their packages, like the Major Rager box of 18, or the B.M.O.C., which comes with 24. They also have an option to order 300 cookies for 300 bucks, in case you have a really big apartment.
Why this is so, so good: Fresh cookies, with milk (that you probably won't drink because you have other beverages, but still it's the thought that counts), delivered fresh to your door, still gooey and warm from the oven? Shut up.
The catch: Your guests are going to love melted chocolate chips in their cookies. Your furniture, however, might not. Neither will your walls, table, or dog. Think of the smears as badges of honor, awarded to only the best parties. Wear them with pride.
