Jim Henson originated the character in 1955 on his local television series, "Sam and Friends". Henson himself described Kermit as "kind of easy-going, very likable...sometimes slightly a wiseguy." Frank Oz remarked that Kermit possesses a natural sense of leadership within the Muppets, explaining that "he has all these zany characters and a world around him and he tries to be the center and hold everything together...sometimes he gets too much and blows his top, but essentially he kind of goes with the flow." Brian Henson described his father's performance as Kermit as "coming out of his own personality—was a wry intelligence, a little bit of a naughtiness, but Kermit always loved everyone around and also loved a good prank."
