Since the beginning of pro wrestling, carnies used to fill the interior of cornbuckles with actual corn (hence the name), as it was the softest material available at the time. But, since the advent of new wrestling ring technology and new age materials, corn-filled corn buckle started being phased out as promoters from around the world considered this practice time cornsuming. This corn material was slowly being replaced by state-of-the-art high density foam padding, which was softer than the former corn filling. As of today, WWE is the only wrestling company in existence that still carries on with this tradition. They sometimes swapped the traditional corn filling with regular foam padding, this to rib the late wrestler George "The Animal" Steele, who's known for ripping cornbuckles apart with his teeth and sometimes eating the internal filling which caused cornstipation and rectal bleeding, to which he recalled during an interview: "popped the boys real good"
