[Capt. Tom]

I worked with a person who after seeing "Jaws" told me he used to think about shark attacks when he would take a shower at home.

When a person has an irrational fear of something like sharks, dogs, cats, snakes etc. they can work themselves into unfounded fears. - Tom

Gee...When you take a shower you’re supposed to think about the Hitchcock movie - Psycho!

or the Mel Brooks film - High Anxiety!
