If I'd opned the door and seen that a number of things would have happened - in order:
1) I'd have sh*t myself
2) I'd have reached for flame-thrower, shotgun, spare nuke, .5 Browning, whatever
3) No more snake, truck, half of Oz !!!!!!!!
Could also have set a new 1000 metre record that would have ensured entry to the Athens Olympics
