FORTUNE'S GUIDE TO DEALING WITH REAL-LIFE SCIENCE FICTION: #6
What to do...
    if a starship, equipped with an FTL hyperdrive lands in your backyard?
	First of all, do not run after your camera.  You will not have any
	film, and, given the state of computer animation, noone will believe
	you anyway.  Be polite.  Remember, if they have an FTL hyperdrive,
	they can probably vaporize you, should they find you to be rude.
	Direct them to the White House lawn, which is where they probably
	wanted to land, anyway.  A good road map should help.

    if you wake up in the middle of the night, and discover that your
    closet contains an alternate dimension?
	Don't walk in.  You almost certainly will not be able to get back,
	and alternate dimensions are almost never any fun.  Remain calm
	and go back to bed.  Close the door first, so that the cat does not
	wander off.  Check your closet in the morning.  If it still contains
	an alternate dimension, nail it shut.
