Killer Jokes

The "Killer Jokes of the Trixter" are really dangerous books, that appear in Ultima VII/2 and Ultima VIII. They are vastly different from any other book encountered. The books read all like this:

KILLER JOKES

by Trixter

''Welcome reader and learn the age old art of practical jokes. I, Trixter have studied long and hard from the tomes of the ancient masters to achieve the knowledge and wisdom that I may now impart on you, the novice.''

Chapter One:

Exploding Books

(Heh, heh...)

Afterwards, they all will explode and in the worst case, cause death to the reader.
