This just in from CNN:
In 1996, toilets injured 43,000 Americans, buckets and pails hurt almost 11,000 and room fresheners were responsible for 2,600 injuries in the nation. Sharks injured 13 people that same year. (There are a variety of toilet-related injuries: Seats can fall, smashing boys' genitalia mid-micturition; cracks in toilet seats can pinch a user's buttocks; and, as the ladies have explained time and time again, gentlemen, leaving the toilet seat up can cause folks to crash into the toilet bowl, damaging their buttocks and/or tailbones.
I feel better about the risk of shark attack, but this article is way too graphic about the toilets!
