A Night On Noah's Ark

Why did Noah take nits? Let's pull this Ark to bits, God let Noah take two nits, Plus two mosquitoes, each proboscis, Gave humans encephalitis, What is worse than this? Why they bring malaria, blip! What is worse than this? As well as Noah's two nits, God let Noah take two rats, With two fleas on board, that's that, So Noah brought bubonic plague, While lovely unicorns floated away, Then on all those wooden decks, Noah took two woodpeckers, by heck, So that was the end of Noah's Ark, Lucky he wasn't eaten by sharks, So, why God, did you plan all this, mate? I know Noah was human to make mistakes, Taking rats, fleas, mossies, and nits, great! Was taking two nits more than fate?
