Joshua gets a fishy no-prize for making me realize that suddenly, I'm even less inclined to shoot the Potomac rapids:

Something fishy is happening in the headwaters of the Potomac River. Scientists have discovered that some male bass are producing eggs—a decidedly female reproductive function.

Scientists have their suspicions about what's causing this, mostly having to do with domestic sewage treatment techniques. Apparently, they're beginning to find some correlation between these weird fish and trace levels of both natural and artificial estrogens coming from households (perhaps caused by urine and birth control pills, respectively). However, much more data will need to be gathered before any firm conclusions can be drawn.
