This article pretty much epitomises everything cracked.com is good at: a cheerfully irreverent pisstake of history, sex and the internet, which still manages to be informative in a nudge-nudge, yuk-yuk, dodgy Photoshop sort of a way. God bless 'em.
Before Einstein finally settled on his cousin Elsa, he apparently almost married her 22-year-old daughter instead (Elsa was his first cousin through his mother's side AND second cousin through his father's side. In addition to the theory of relativity, Einstein was the only human capable of conceptualizing the branches of his own family tree that he had sex with).
That is more about Einstein's sex life than I ever wanted to know. Thanks, Cracked, for another delightfully prurient yet library-safe web diversion!

this page on Teddy Roosevelt, who Cracked regards to be "the single most notable person ever to live".
Checking Teddy Roosevelt's resume is like reading a How-To guide on ass-kicking manliness. He was a cattle rancher, a deputy sheriff, an explorer, a police commissioner, the assistant Secretary of the Navy, the governor of New York, and a war hero. Out of all of his jobs, hobbies and passions, Roosevelt always had a special spot in his heart for unadulterated violence. In 1898, Roosevelt formed the first U.S. Volunteer Cavalry Regiment, known as the Rough Riders. Most people already know of the Rough Riders and their historic charge up San Juan Hill, but few know that, since their horses had to be left behind, the Riders made this charge entirely on foot. You just could not stop this man from violencing the hell out of a San Juan Hill.
"Violencing", heh. Oh Cracked, never change.
ETA: I've read some of those dirty letters James Joyce wrote to Nora Barnacle, and they are fucking disturbing.
