Premise: A man named Ted tells his kids how he met the love of his life, through flashbacks, years in the future. The bored kids sit on the couch and listen as dad regales them with tales of his pursuit of romance. The sitcom's secondary character, Ted's smarmy friend, Barney, is a real standout, often stealing the show.
