A Murder of Crows

Ran across this site today, which has the important purpose of communicating the technical term for groups of different things. Did you know the following (real) collective terms?

• An implausibility of gnus.
• A cartload of chimpanzees.
• A business of ferrets.
• A flamboyance of flamingos.

Updated: I added the "Ferret in a Sweater" label. I've been wanting to use that one for a while now and figured this was as good a time as any.
