What?

Why not?:

You could poke your eye out.

You could cut your head off.

You could saw 13 spokes out of your wheel.

You could get hit by lightning.

Alford's Theorem # 1 - The worst that can happen, as in "What's the worst that can happen?" is drastically undervalued by a factor of 13. Eg. in the above scenario you might think that the "worst that could happen" would be for the widowmaker hanging over the trail to twist unexpectedly and land on Highroller, perhaps scratching him up, or maybe even resulting in a cut from the bow saw. Wrong! This factor = x. The worst that could happen is for the tree to twist unexpectedly and fall on Highroller pinning him to the ground by the groin while simultaneously breaking the tensioned saw blade and shooting a shrapnel fragment like a shuriken right thru the $350 digital camera used to take the photo and into the forehead of the photographer. While the photographer shrieks in pain, accidently switching the camera mode to video, thereby capturing the calamity for later review by the authorities, fire ants stream out of the fallen tree into Highroller's crotch while an oblivious ATV rider screams around the corner and wheelies over the debris. Lightning strikes the resulting wreckage. Anal-probing aliens, attracted by the subsequent explosion, descend and thoroughly anal-probe all on the scene then upload the video to YouTube just moments after Highroller's mother, in the process of being introduced to YouTube by her extended family during a family reunion, executes a search for her son's name. Thus the true value of "worst" = x times 13 or x13. Thusly Alford's Theorem #1 can be simply expressed as W = x13. Just keep it in mind.
