In case the first one wasn't revolting enough...

TDF: A MEAL TO DIE FOR, Part 2 -- SOUP IS SERVED
by Bill K.

"Soup is ready!" Nyssa cheerfully called across the room as she entered
the dining room carrying a large pot filled with boiling-hot soup and
placed it on the table in front of a hungry Tegan and the Fifth Doctor.
With a ladle, she then serves the soup into each of their bowls.

Tegan and the Doctor, to their enjoyment, consume a few mouthfuls of
Nyssa's homecooked soup.

"Mmmm. This is the best soup I have ever tasted in a long time."
commented Tegan. "Did you make this all by yourself?"

"Well, actually, Adric's had a hand in it." Nyssa modestly insisted.

The Doctor then scoops out of his bowl a long, bony morsel with what
distinctly appears to be a human fingernail attached to the end, and
almost succumbs to vomiting.
