No. 2: Barophobia - Fear Of Gravity

Most people would probably agree gravity is a good thing. Without it we'd all be floating around and eating or going to the bathroom ... well, let's just say the less said the better.

Actually, that's one of the very reasons barophobes fear gravity: They worry that the fickle force of nature could one day fail and leave us all literally up in the air.

On the flip side of the coin, some barophobic people worry they instead will be crushed by the force of gravity were it to become too great.

While the fear of gravity may stem from a traumatic fall as a child, sometimes the fear is less direct. Some arrive at barophobia because they fear the role gravity plays in aging -- think sagging flesh -- or just feel powerless over nature.

One thing's a given though: You won't find many barophobes in line to ride Space Mountain, or any other thrill ride for that matter.

Just as you won't find many people with our last phobia enjoying a nice PB&J ...

No. 1: Arachibutyrophobia - Fear of peanut butter sticking to roof of your mouth

We are more than a little skeptical anyone realistically could have an abnormal fear of peanut butter sticking to the roof of their mouth, but, to be frank, the idea's so delightful we're willing to embrace arachibutyrophobia.

The phobia, which hasn't actually been officially categorized as a medical disorder, was coined by author Peter O'Donnell in his 1985 novel "Dead Man's Handle." It got online and spread easier than creamy peanut butter on warm toast.

The term itself comes from the Greek word arachi, which means "ground nut," and ... who are we kidding? It's impossible for anybody to take this one seriously.

That is, except for the good people at the CTRN Phobia Clinic, who, seeing an opportunity to make money off the gullible, latched onto the word as a serious, debilitating illness. As the clinic's website promises, for as little as $1,497 you too can work toward the "guaranteed lifetime elimination of Sticky Peanut Butter Phobia."

Now, that's truly scary.
