If a huge meteor is coming towards earth, I think it's a good idea to run around in the yard, yell and flail your arms; because THAT'S what is really going to help the situation.
If your daughter is stuck in the wall because of a poltergeist, I think it's okay to invite a bunch of people over and have a party. Not only will your family be the most entertaining people on the block, but now is your chance to show off your new furniture!
When you are a sheriff looking into a family that disappeared and you find nothing, but your deputy finds a small lump of sugar; it's pretty obvious then that it was giant, man-killing ants.
When zombies are chasing you, a fun thing to do is pretend you're wounded, start limping...then, fall down. Then when the zombie reaches down to grab your foot, get up and run away...cause they love that.
If you are by a creepy house in the woods, and there's a sign that says, "Danger", then you hear a strange noise in there; I think it's okay to go ahead and go in...in fact, go naked...and go ahead and bring a kitten too.
