Group Dynamics

As I walked back from lunch today with three other economists, we passed by the college dean, who asked if this would be called a "gaggle of economists." This got us speculating about the appropriate group names for professions. These labels exist already for groups of animals ("murder of crows," "exaltation of larks," etc.). Why not for humans? We had the following ideas:

An optimization of economists
A set of mathematicians
A bewilderment of philosophers
An agglomeration of sociologists
A buggery of lawyers

Sorry, I just couldn't resist that last one. Anyway, I'd love to hear people's suggested additions to (or revisions of) the list. I'll post the good ones.
