A funny video has emerged of a young boy going on his first roller coaster ride with his father. <br /><br />The footage, shot on Tuesday in Oklahoma City, OK, USA, shows the boy screaming as the ride starts while his dad is laughing "hysterically".<br /><br />After the first go, the boy is really enthusiastic but when the ride goes unexpectedly backwards he becomes scared and says he never wants to do it again.
