I've always thought Groupon was funny. I could start a business where my sole business plan was that for every 95 cents you gave me, I would give you a dollar, no strings attached. I'd probably have a billion in "revenue" even quicker than Groupon, and I would probably be more profitable too. This might be a gross oversimplification, but it's still true.
