Another variation similiar to the sneeze is this famous one:
For Want of a Nail
For want of a nail the shoe was lost.
For want of a shoe the horse was lost.
For want of a horse the rider was lost.
For want of a rider the message was lost.
For want of a message the battle was lost.
For want of a battle the kingdom was lost.
And all for the want of a horseshoe nail.
I've also seen it done with a paper clip...losing a page, then losing a contract, then a business folding, all for the want of a paperclip.
