Fair James is looking forward to a relaxing weekend at home, until he finds out his agent, Mark has booked him to appear as "Mongo Man" at the county fair. He invites his brothers Todd and Gary and Gary's family to come along, but Gary doesn't want Sammy coming because of his bad influence on the kids. Gary's fears become real when Sammy stows away in the family car and then accidentally is left alone with Gary's kids, who end up stranded upside down on a broken ride while Sammy is at the bar.
