True story:

Scene: a pleasantly darkened nap room in a day care centre. Two dozen preschoolers dreaming away with their blankies on their little cots. Reading quietly in the middle, a young man on a chair, who glances around now and then to see that all is well.

Rustling sounds. Young man looks to the source. Small girl is wriggling about on her cot.

"Are you okay, Ellie?" he whispers.

"Yah!" she whispers back.

"Okay, then try to go to sleep."

Muted rustlings ensue, then silence. A moment passes.

"Trevor?"

"What is it, Ellie?"

"Here!" she hold out her closed hand. The young man holds his hand out. She drops something in it, something warm. He strains to see in the dim light, but can't make it out.

"What is it, Ellie?"

"I don't know.....

"...it came out my bum."

(Did I mention this young man is rather squeamish, and hasn't been a day care worker for very long?)

He rises quickly, opens the door to let some light in. As he does, the thing in his hand moves. The beginnnings of a high thin scream is barely supressed as he rushes to the staff room across the hall.

Biggest roundworm I've ever seen - eight inches long at least.
