Female mosquitofish give birth to tiny babies, like the guppies you may remember from your third-grade aquarium.

It sounds like an urban legend, but rats actually do manage to crawl up from the sewers and into unsuspecting residential toilets. In Portland, Oregon, one pest control company says it gets ten to 15 calls a year for rats in toilets, and it’s easy to speculate that the numbers are higher in cities like New York.
