I used to think that earwax was uniquely revolting, but I was proved wrong when I started my student training in the gastro X-ray department.
As part of our initiation we were told to sample all the contrast media (basically anything that can be injected/introduced into the body, and which shows up on X-rays). This means all the barium-based stuff as well as the oily and water-soluble iodine media.
And that is the day I discovered the worst one ever. It is a product called Hexabrix and it is exactly like earwax. Imagine having to drink 20ml of that! I only tried a few mls and I wanted to spew. It is guaranteed to make anyone's face screw up like a cat's anus.
