Remember the classic kids' game Mad
Libs? They were stories which came in a pad, with blanks
labeled with parts of speech (noun, verb, adjective). One
person read off whatever the blank required, and the rest
of the group shouted out answers, the more random the better.
Then the person with the pad read back the resulting lunacy.
Here's ENT Libs, the "Enterprise" version
(and I'm surprised no one's done Trek Libs before!). Verbs
are in present tense unless indicated.
