Harwood had a successful career on the show becoming one of the longest serving presenters at 6.5 years. He soon became popular and renowned for his bad jokes and mischievous behaviour. Through the years he grew his famous catchphrase, "I want one", as well as growing to call over to "Camera Two" to get a shot of him and giving away strange prizes in the show's game "Spot Shelley", including a house in Spain, a unicorn called Colin and a life-times supply of chutney. His various hairstyles often added to his fame among viewers. Barney is particularly good at cycling, doing well in various challenges with bikes, a big fan of coffee, as well as music and has interests in photography and camping out in his campervan. He, however, has a fear of frogs; on his first show Steve Backshall got him to hold one and on his last show he was made to kiss a frog, conquering fear in both.
