Goldfish woes?

I just won two goldfish at the fair. So I let them live in the bowl for a couple days then I bought them a 3 gallon aquarium. I was looking up goldfish on the web and saw that they need 10 gallons each and bowls=death. My apartments only allow up to a five gallon. What should I do with the fish? I don't want to hurt them by keeping them in a space that will kill them. Is there any way to like release them into the wild? Suggestions??
