Redd Foxx began doing stand-up comedy on the infamous Chitlin' Circuit in the 1940s and 1950s. Foxx was one of the premier blue humor comedians. Blue humor was very dirty, too dirty for white audiences. For years his party albums were not available in white record stores.
A near fall (near pin) is when... one shoulder touches the mat and the other shoulder is at a 45 degree angle coming down to the mat, or... the wrestler is held in a high bridge or back on both elbows. If a near fall lasts for two seconds, you get 2 points.
You can score points toward victory in both wrestling and BJJ, but competitors in both sports strive for a match-ending and match-winning move throughout the match. In wrestling, a fall ends the match if one wrestler holds the other on his back for three seconds. BJJ uses submission, which means one grappler has placed his opponent in a hold that hurts so much -- or threatens injury so certainly -- that he surrenders the match.
