Declaration of Independence

Any campaign fought by this idiot.

The moment you were conceived.

So get this:
It's 1949, and Mickey Cohen is at a club in LA. If you don't know who Mickey Cohen is, just google the man. So out of the same club walks Shirley Temple, 21 and virtually retired from the pictures. She gets her blue Cadillac from the valet and drives off. Then she notices that the upholstery isn't like she remembers it. Then she notices a briefcase on the passenger's side, and inside is a loaded gun.
This isn't her car, so she brings it back to the valet. He realizes that there's only one other blue Cadillac in the lot, and it belongs to god damn Mickey Cohen. He apologizes as quick as he can to Miss Temple and goes to put the Cadillac back in its spot before anyone notices. While he's doing that, he whips it around a corner a little too fast and puts a tiny scratch on the fender.
A little while later, out comes Mickey Cohen, along with his lieutenant, bodyguards, a police escort, a reporter, and some song and dance broad. He notices the scratch on the fender, because noticing things is how he got to be where he was. Mickey goes down on one knee to look at the scratch. While he's doing that, a bullet hits him in the shoulder. There are two assassins opening fire from across the street.
It's a bloodbath; everyone he was with gets shot multiple times, along with a bunch of unlucky sons of bitches in the crowd in front of the club. Mickey stays low, then grabs a bodyguard and throws him into the car before they drive off.
If he hadn't been kneeling, he would have been riddled with bullets.

tl;dr History consists of multiple incredibly stupid moments per day, like that time Shirley Temple accidentally stole Mickey Cohen's car and saved his life because the valet spilled his spaghetti.

Reads like hagiography, but whatever, it's well written enough. Have some dots, on the house.
