Hmmm, I think the rules for the winner's circle need to be clarified a bit.
A clue can be buzzed if:
Any part of the answer is given in the clue. For example, THINGS THAT OBEY: "An Obedient Dog" (D'oh!)
The clue contains a prepositional phrase. This does not include "Things ____ would say" or "Why you _____". This rule is not as clean cut a rule on the current incarnation of Pyramid.
The clue contains a synonym of the key word. This is determined by the key word appearing in the dictionary definition of the clue word or vice versa.
The clue is nonsensical, such as a phrase that has all of the prepositions removed but cannot stand alone.
Usually if a clue is described as "Too Descriptive", it is because it has violated either the second or third rule in some way.
If there are any corrections to this, please post them. Also, isn't there a site that has a bunch of Game Show rules? If so, are the WC rules there?
