We used to have one a few years back the tamest and friendliest budgie around used to wolf whistle, Chase a ball around the room used to leave the cage open all day. Used to take him outside and he'd just sit there next to you and dogs also used to sit on dogs.
Unfortunately he killed him self trying to get a drink out of a half pint glass and drowned upside down. When he died the house lost a character that always cheered us up.
