War of the Worlds

Twas on a day that was cold as ice,
Everybody cowered in full flight,
They dived under covers left and right,
And everybody saw the gruesome sight,

It came from Mars, Mercury or Venus,
I dont know but I think it has seen us,
The tin can moved and everybody hushed,
Half of mankind just got flushed,

Feasting on warm blood makes my bones chill,
The martians are one and the humans are nil,
Nowhere is safe; not land nor water,
Why is this happening; this big slaughter,

When will they die,
This is defiantly not fair,
Look they are falling,
From the microbes in the air.
