How about this giant pig shot in Alabama...
An 11-year-old boy used a pistol to kill a wild pig his father says weighed a staggering 476 kilograms and measured 2.74 metres, from the tip of its snout to the base of its tail.
He said he shot the huge animal eight times with a .50-calibre revolver and chased it for three hours through hilly woods before finishing it off with a point-blank shot.
