Trading Spaces: Goldfish Bowls. Gee, fellas, the water in the next bowl really isn't any cleaner. Of course, if your bowlmate is driving you nuts, well, he's driving you nuts. Hopefully, there really are lots of fish in the sea. Too bad you're not there.
Seriously, though, when two goldfish just trade bowls like this, they are actually trading lives. Yes, life looks pretty much the same in both bowls, but it does matter who one is sharing it with. The only other difference might be a very small change in perspective, physically. Perhaps the one on the left sees a bit more sunlight. This may or may not be important to one's mood.
The above fish are murmuring something--ah, yes, I must be tired, or restless, to even be speculating about their business. For all I know, they leap from bowl to bowl on a dare or just for excitement every once in awhile. Don't we all do pointless things for a bit of fun?
