Late CROCODILE HUNTER star Steve Irwin's four-year-old son has proved he is just like his father - after laughing off a potentially poisonous snakebite. Four-year-old Robert's passion for animals was in evidence when the child was attacked by a baby boa constrictor - instead of recoiling in shock, he was proud to have been the victim of a potentially deadly bite. Irwin's widow, Terri, explains, "He picked one of them up and it bit him on the finger, and he was so proud to have copped his first hit. "He said, 'I hope it wasn't venomous,' so I assured Robert I wouldn't actually let him play with venomous snakes." It's not the first time Robert has had a close encounter with a potentially dangerous animal. His late father sparked outcry in 2004 after being filmed holding his then one-month-old son while feeding a snapping crocodile. Irwin died in September 2006 when he was stabbed in the heart with a stingray barb.
