Justin:

Evil does its silent worst
The calm before the storm
Then when you least expect it
The bison comes to call

Jim:

Well you might think you are a bad mother
And you might think that you are looking pretty cool
And you might think you are a fighter and a lover
And you might think you can't be taken for a fool

But this will take you by surprise, my friend
And this is uglier than any other horror
This is a nightmare that will never end
For you are entering a world of bisonic terror! (Please God no!)

Justin:

It's hiding round the corner
In the shadows of fear and fright
Just make sure you're on the lookout
As it stampedes through the night

Jim:

The light's not working and you're home alone
Then very suddenly you're startled by a ring
With trembling fingers you pick up the phone
But there's just silence, nobody says a thing

What is that sound that you can hear outside?
It's like the echoing of hooves upon the floor
Ghostly grunting and a spectral snort
Your heart is thudding as you slowly open up the door (oh no!)

Justin:

It's the tap-tapping at your window
It's the door handle that turns
It's the chill running down your spine
It's the terror of the herd

Jim:

An evil bison with its teeth gnashing
Its hoof is stamping and its jaws are open wide
Its legs are spindly but its horns massive
And hula hoops of doom are coming from its eyes

You try to run but you just freeze in fear
You try to scream but you cannot make a sound
If there's a lesson to be learned in here
It's not to be there when the were-bison comes around (aaaaargh!)
