I don't usually engage in this sort of thing here, but I have always enjoyed knowing the names of groups of animals.

For example, a herd of deer. Boring.

A few fun ones.

An ambush of tigers.
A murder of crows.
A crash of rhinos.
A clowder of cats.
A paddling of ducks.
An implausibility of gnus.
An exaltation of larks.

Add some if you like. No cheating with the internet.
