Brain Twister Illustrated

"Mark Phillips" is, or are, two writers: Randall Garrett and Laurence M. Janifer. Their joint pen-name, derived from their middle names (Philip and Mark), was coined soon after their original meeting, at a science-fiction convention. Both men were drunk at the time, which explains a good deal, and only one has ever sobered up. A matter for constant contention between the collaborators is which one. They have been collaborating for some time now, and have devised an interesting method of work: Mr. Garrett handles the verbs, the adverbs and the interjections, Mr. Janifer the nouns, pronouns, and adjectives. Conjunctions are a matter of joint decision, and in the case of a tie, the entire game is replayed at Fenway Park, Boston, early in the following year.
