I particularly enjoy the collective terms for people. Many of them are poetically vivid.

A smirk of couriers
A sentence of judges
A doctrine of doctors
An obeisance of servants
An incredulity of cuckolds
A brace of wives ?!??!!
An illusion of painters
A boast of soldiers
A drunkenness of cobblers
A wandering of tinkers
An impertinence of peddlers
A neverthriving of jugglers
A riffraff of knaves
A poverty of pipers (Which leads me to suspect that “Paying the piper” wasn’t as onerous a duty as the cliché leads us to suppose.)

Then there are these, which give a whole new peephole into the Englishman’s enthusiasm for Great Harry Tutor’s break with Rome.

A pontificality of prelates
A bundle of archdeacons
A skulk of friars
A superfluity of nuns
An untruth of summoners
An abominable sight of monks
