My boss's father had the fear of getting peanut butter stuck to the top of his mouth - Arachibutyrophobia. Seriously, this was something that concerned him, something that may have caused him to lose sleep. Other unusual phobias:

Fear of Thousand Island Salad Dressing
Fear of Ramen Noodles
Fear of Undercooked Tater Tots
Fear of Pie

This is how someone describes their fear of pictures of sharks:

I have another form of Selachophobia (Fear of sharks) If I touch a
picture of a shark's head (especially with its mouth open) it can still
bite my fingers off. I remember once in fourth grade we were reading a magazine, and I was holding it up the whole time I was reading. And since I was a faster reader than any of the other kids in the class, I got to the last page and dropped the magazine, kicked over my desk(hitting the child in front of me and injuring her) and scrambled onto the kid behind me's desk, all the while screaming bloody murder. I had been touching a shark's picture the whole friggin' time! Three teachers came running from different classrooms. I got into so much trouble just because it was "ONLY a PICTURE of a shark." I also have the phobia of a shark popping up in the pool and I won't take baths. Lakes are avoided at all costs and...the ocean? Yeah right.

I have only normal fears: success, commitment, the opposite sex, etc.
