There are numerous occasions in which such money issued and of course we use them  because we all love having fun. I'm talking about toy money, or play money, if you prefer, for various table games we all like to play with our relatives and friends. There is also a kind of toy money for parties which you receive for performing a dance routine, singing a song, reciting a poem etc. Although you can't go to a normal store with that kind of money, you can buy a lot of things with them at the party, like drinks, snacks and sometimes even kisses of a beautiful woman.  But apart from for fun, I would never use paper money which wasn't backed by any government. I mean I wouldn't sell a thing for them to a stranger because there could be no guarantee that you will be able to buy something with them tomorrow.
