A bitcoin, a light coin, and a ripple walk into a bar.
The bitcoin asks for a beer and the remaining .92 BTC enjoys his beer.
The litecoin asks for a beer, the bartender refuses to serve the litecoin because he's not rich enough.
The ripple asks to exchange an one beer IOU for a beer. The bartenter looks at the IOU. Felling sorry for the ripple he accepts the IOU and serves the ripple a beer. The ripple then says that'll be 100 XRP.
I wish I had more sig space, because this would definitely be going in it!
