You are now cursed with the finger of DOOM.
All that you touch is sure to go BOOM.
Everyone here better clear the room,
When you point
The finger of DOOM.
The finger of DOOM is a weapon so mighty,
Its owner can rule the world.
Destroy all your enemies.
Win every fighty.
Just don't touch ME, alrighty?
-B.C. Byron

With great finger power comes great responsibility.
I read this poem to my daughters at the dinner table yesterday and, of course, one of them poked me in the shoulder and giggled as I read the last line. They were soon pointing their fingers and chasing each other. I love interactive poems that get kids moving and acting them out. I remember a Shel Silverstein poem that had this effect and it really stuck with me. The Deadly Eye of Poogley-Pie gets everyone laughing and staring each other down as you read it, and for many days after.
I also like the word DOOM a lot. It just needs to be written in capital letters and be spoken with scary emphasis. Call me weird, but DOOM just makes me laugh when I hear it.
