While talking about the Italian Cruise Ship that sank over the weekend, Jackie expressed her intense fear of being on the ocean.

That got me to thinking, I have a handful of phobias that I don't understand.  Take sharks for example.  We live in Idaho.  There are no sharks.  So why is it whenever I'm swimming in water and I can't see bottom I imagine an entire school of hammerheads just waiting to tear me apart?  And heaven forbid a piece of moss touch one of my legs.  When that happens I'd lay money that I can make it to shore faster than your jet-ski.

My head tells me I'm being ridiculous but my gut  says there be sharks in them waters. 

One article suggests that 7%-13% of people expereince irrational fears to I can't be alone here.  What are your irrational phobias?
