Animal collective nouns, courtesy of Wikipedia. Personal favorites: an unkindness of ravens, a party (hee) of lady dolphins, an ostentation of peafowl, an audience of squid, an intrusion of cockroaches, A MARMALADE OF PONIES. MARMALADE. OF. PONIES.*
If anyone finds us a website that details the etymology of these we will put that person on our fiancé/es list faster than you can say "eusuchian."
This more general list of collective nouns is pretty fantastic also (A FILE OF CIVIL SERVANTS!!!).
