BCG wasnt born, he shockered his way out of the womb and proceeded to kill everyone in the room with his bare baby hands, all save his mother. BCGs childhood was spent single handedly winning World War One.
He came into manhood in the 1930s. The Great Depression was actually started by men all over the world realizing their inadequacies compared to BCG and becoming depressed, and all of the ugly women in the world realizing they couldnt sleep with him and becoming depressed. After personally killing all the Nazis and throwing an atomic bomb at Japan to end World War Two, he spent his next few decades fighting ninjas. BCG did not partake in the Vietnam War for if he did, all of the Vietnamese would be dead.
BCG was also the first known Jedi and was the father of Yoda, Yoda used to be the size of three Wookies until he mouthed off and BCG was forced to shocker him into the small green creature he now is. Wookies grow their hair that way in tribute to BCG.
BCG ceased being a Jedi when he met the Force personally, noted its lack of chest hair, and shockered it. This created the Dark Side, as all bad ass Sith actually attempt to channel BCG to gain great power.
Later in life, Superman challenged BCG to an arm wrestling contest. Superman no longer has an arm.
In 1950 BCG went to Holland and had sex with 54 nuns; when the children grew up they became the '72 dolphins
That's the true story of BCG as it is told throughout the world.
