When the fight ended, numerous fans booed and started yelling, "Fix!" Skeptics called the knockout blow "the phantom punch." Ali called it "the anchor punch." He said it was taught to him by comedian and film actor Stepin Fetchit, who learned it from Jack Johnson. However, Ali was unsure immediately after the fight as to whether or not the punch connected, as footage from the event shows Ali in the ring asking his entourage, "Did I hit him?" Ali told Nation of Islam minister Abdul Rahman that Liston "laid down" and Rahman replied, "No, you hit him." Rahman later said, "Ali hit him so fast, Ali didn't really know he hit him. ... and It took a long time before even he saw the punch he hit Sonny with." Tellingly, Ali never threw the 'anchor punch' again nor did he subsequently refer to it.
