Funny Lesson De Jour

The English language has some wonderfully anthropomorphic collective nouns for the various groups of animals.

We are all familiar with a Herd of cows, a Flock of chickens, a School of fish and a Gaggle of geese.

However, less widely known is a Pride of lions, a Murder of crows (as well as their cousins the rooks and ravens), an Exaltation of doves and, presumably because they look so wise, a Parliament of owls.
Now consider a group of Baboons. They are the loudest, most dangerous, most obnoxious, most viciously aggressive and least intelligent of all primates. And what is the proper collective noun for a group of baboons?

Believe it or not a Congress!
