Pros:  Great fun, Amusing way to "discuss" your friends
Cons:  New player needed for each game, other people who
  are in line for playing can't watch the game.

This is a secret group game.  A number of players (who know the
secret) will form a circle, and a new player (who doesn't know the
secret) will be told:

You are the psychiatrist, and we (the circle of players) are your
patients.  We all have the same condition, and it is your job to
figure out the condition.  You can only ask us yes and no questions.

The psychiatrist will start asking questions, and the patients
will break out into laughter at some of their answers, for no
apparent reason.  If that wasn't weird enough, occasionally the
patients will yell out "Psychiatrist" and all the patients will
get up and run around and find new spots to sit.

When the psychiatrist finally learns the secret, he/she joins the
group and a new psychiatrist (who obviously hasn't been watching
the game) can play.

The secret is below:

The condition is that each player believes that they are the person
sitting to the right or left of them (agree on this beforehand!).

Answer any question that you are asked as best as you can according
to how you think the person to the right/left of you would answer.

Whenever the psychiatrist asks a question that a player can't answer,
or if the psychiatrist is getting too close to figuring it out, or
just if it's funny, someone can yell "Psychiatrist!" and then everyone
gets up and picks new places to sit (and hence, new people to emulate)
