Right, here we go...
In order of pant-browning, stomach churning, utter fear and disgust (in ascending order):

Monkeys. All types of the little cnuts. Sometimes it's the huge fangs, other times the beady, intelligent eyes, working out how best to completely destroy my life. Most of the time it's their fingers: the right shape and length for poking out my eyeballs and reaching into my eye sockets pull out chunks of my brain and eat it.

Clowns. Lifeless eyes, a permanent grin (as with ballerinas, smiling all the time is just plain unnatural), and a sense of all-consuming despair. Even with the dolls of clowns. This stems from watching films like "It" and "Poltergeist". Show me a picture of one and I'll scream a little.

Spiders. Do I really need a reason to hate these? Ok, they have more legs than anything has a right to. I also dislike earwigs, centipedes, scorpions, daddy-long-legs, and octopi.

Injections. I will feel horribly sick if I see needles, pictures of needles, pictures of people injecting, films of injecting etc.

Cliff Richard. We used to have a Cliff Richard calendar up in my last office (where I worked with GrandMasterFluffles). I could cope with it then, I just didn't like it that much. Now, however, for some reason the very thought of him makes me want to vomit, and sends shivers down my spine. The smug git.

Teeth. I like having them, but live in absolute fear of them cracking, breaking, or falling out. Consequently, I find myself grinding my teeth with stress, and then feeling nauseous when I realise that any minute, they could all crumble and fall out of my mouth. So I get more stressed, and grind them even more. It's a vicious circle. I'm also terrified of anything happening to my fingers, tongue or lips, but I think this is because I sing and play the flute, and damaging any of them could ruin my career!

I think I have more, but those are the really major ones.

EDIT: Just remembered another one: small heights. Like k626, I can stand on a tall building with no fear whatsover. However, try to get me to stand on a chair or a ladder, and I'll get and shaky and dizzy at once.

Oh God, Clowns...
Their horrible faces, masking their sorrow... The horrid, foul, evil creatures.

I read Stephen King's 'IT' once, tried to stand up to my fear. Didn't sleep for a month.

An interesting fact:
Octopuses can squeeze through a hole the size of a quarter since the only hard part of their body is their beak. Theoretically one could come up your toilet.
