10. Crowdmug App
Sick of shelling out for bar covers only to discover that they're completely abandoned—or worse, swarming with dudes and no redeemable females? This app was made for you, cousin. If surveying scenes live and in person has proved to be a letdown to you and your entourage one too many times, you can opt to invest that same cash (probably more) to get photos and real-time video of all your prospective stops for the night. The app will submit your request to the crowd, and those out at your bar of choice can respond and make what's got to be some of the easiest money of their lives.
Or you could, you know, just leave the house.
