Whoops!

I've gone and put some Arsenic
On my steak and kidney pie
And accidentally swallowed it
So now I'm going to die.
I thought that it was Parmesan
I thought that it was cheese,
But it was deadly Arsenic stuff
And I can't feel my knees,
I'm losing feeling in my feet
My hands and arms are numb -
All because I wanted cheese
With pie inside my tum,
Oh Sainted Lord! Oh Holy Cow!
I didn't want to die!
I only wanted Parmesan
Upon my little pie!
