In New York City, Fewer Murders on Rainy Days

I didn't read this article, but I'm guessing the murderers get all organized--gloves, weapon, disguise--and then realize when they've gotten downstairs that they've forgotten their umbrella. But if they run back upstairs to get it, it'll throw their timing off and ruin their alibi.

So much preparation--wasted!

"Oh screw it," they say, and spend the rest of the night drinking Bailey's and watching "So You Think You Can Dance."
