Rat.
Picture the scene. 4th year biology lesson. Mr Macy has just announced that today we are doing dissection, and that anyone who doesn't want to watch (either for ethical reasons or squeamishness) should please remove themselves to a corner of the room.

He takes the body of a white rat out of a plastic pouch and proceeds to nail the poor little guy spreadeagled onto a butcher's block. He describes each step of the dissection as he proceeds ("Now we're cutting through the chest, there's the heart and look here's the intestines"). Each organ that he removes he carefully places into a glass beaker at the side.

Most of us watching are coping well so far - the blood had been drained from the rat previously so it's not particularly gorey.

When he's done he covers the body and the organ beaker with a paper towel and puts it on a side bench for the lab assistant to remove. The lab assistant enters the room, picks up the board and makes for the door. On the way out she trips, drops the board, the beaker smashes on the floor distributing rat entrails all over the place. The body of the rat also becomes unhooked and flops down to the floor.

This happens in full view of the squeamish group - two of whom immediately vomit and a third faints, hitting his head on the edge of a desk and cutting open his forehead on the way down.

Entrails, blood, vomit. It was like a massacre.
