Most Hated Thing in the World

So all this morning, I was in the hospital. Why? To get some x-rays done of my digestive system. What did I have to drink for it to show up on the x-rays? Liquid chalk. That's what it tasted like. Everytime I tried to swallow it down, my gag refex kicked in and I almost threw up. I was only able to drink a little, and we had to wait hours to be able to take the pictures.

My mom had to go through a similar thing, and we have both made the conclusion that that white chalk liquid is the most hated thing in the world.

After that, water never tasted so good.

What is YOUR most hated thing in the world? Have you had to drink that chalky white stuff?
