One of the lovely things about having kids is teaching them interesting stuff. And one of those things is Collective Nouns.
An Unkindness of Ravens, a Tower of Giraffes, a Conspiracy of Lemurs, a Smack of Jellyfish.
And one of them, it turns out, is a Passel of Possums. Who knew and why did they spell it wrong?!
Apparently there is no accepted collective noun for Octopuses...
