As you reach for the web, a venomous spider appears.  Unable to pull
your hand away in time, the spider promptly, but politely, bites you.
The venom takes affect quickly causing your lips to turn plaid along
with your complexion.  You become dazed, and in your stupor you fall
from the limbs of the tree.  Snap!  Your head falls off and rolls all
over the ground.  The instant before you croak, you hear the whoosh of
a vacuum being filled by the air surrounding your head.  Worse yet, the
spider is suing you for damages.
