It occurred to me that monsters like Random Word Generator and Thesaurus Rex could benefit from having varying text. In the RWG's case, any given instance should have random body parts (though the last one should definitely always be "CHEESE"); for the Thesaurus Rex, it would be amusing if it would substitute words and phrases that were similar in meaning (lunging at the contestant with "dentition of disaster", for example).

In either case, it could be implemented in a manner similar to the Lion, but in the latter case especially there would be added amusement in having it change dynamically.
