Found this over at Adverlab (MIT's blog on the future of advertising) and just couldn't resist. Apparently, you can pick yours up on Ebay, or what the hell- just make one! Wanna make some money with it? Here are a few ways that justiNYC proposes that you could do just that:
1) Sing through it on the train with a cup or one of those little paper bag makeshift change purses and hope you don't get your ass beat.
2) Get someone to pay you to sell comedy show tickets on 34th Street or passes to some shitty spa. Again, hope you don't get your ass beat
3) Finally, maybe you could go help out those African-centric holy men (you know the ones that love their interpretation of the bible and hate white people-yeah them) standing out on the street near Penn Station. They could cetainly use some help. But unless you are black, chances are you'll get your ass beat.
There are all sorts of ways to make money in NY-but if you have none, it ususally involves standing on the street or in the train. Be creative...and loud!
