I want to start a contest for the most imaginative collective noun. I suggest the prize should be one big collective raspberry.
I have a few nominations:
an autocracy of authors
a proud of pedants
a labyrinth of lawyers
a doctrinaire of doctors
a nudge of nurses (think Monty Python, "Nudge, nudge. Wink, wink. Say no more."
a joke of jocks
a cherriloss of cheerleaders
a bristle of Brits
a frump of French
an astute of Aussies
a Camelot of Californians
