Collective nouns- an interesting concept!!

I was just browsing through my home page on facebook and one of my friends had posted the question,"a flock of geese, a herd of cows, a of journalists" ? I started googling and came across the site http://users.tinyonline.co.uk/gswithenbank/collnoun.htm#People

Its interesting to read so many collective nouns..By the way, the answer is "A passel of journalists" !! There are other interesting coll. nouns like "A rope of onions, A phantasmagoria of phantoms, A troop of mushrooms, A goring of butchers, A curse of painters, A gaggle of women, A quiver of cobras, a nest of vipers, A rhumba of rattlesnakes, An intrusion of cockroaches(well, can there be any place devoid of roaches, so thought of giving them access to my blog too!!), A sloth of Bears, A mob of kangaroos, a leap of leopards, A convocation of eagles and a cast of falcons.." Wow, thats quite a list and there are lots more in this website..Quite a collective of coll.nouns!!
