Allen's show also had one of the longest unscripted "crack-ups" on live television when Allen began laughing hysterically during "Big Bill Allen's Sports Roundup". Allen, known for his infectious high-pitched cackling laugh, laughed uncontrollably for over a minute with the audience laughing along, because, as he later explained, he caught sight of his unkempt hair on an off-camera monitor. He kept brushing his hair and changing hats to hide the messy hair, and the more he tried to correct his appearance the messier and funnier it got.
