94. Random facts: animal names

OK, so I know there are...
... flocks of sheep...
... schools of fish...
... swarms of bees...

But today I learnt that one can also say...
... a murder of crows...
... a knot of octopus (octopi ?)...
... an ostentation of peacock...

And I'm asking, what next ?

A giggle of schoolgirls ?
An officiousness of entrepreneurs ?
An iPod of teenagers ?
