My favourite episodes are "Chuck and Kelly, doin' it again," "Cradle to Grave," "One step forward, two steps back," "Hug and Tell," "The New Boss," "House of Tomorrow," "Wall of Fame" and "Hostage Watch."
I love the episodes when there are just massive laugh out loud moments like the Chuck and Kelly ad campaign or Chuck making a fool of himself when he's trying to save Montana/Sally's job. I like the episodes where all the cast are involved in the same story like in Hostage Watch and Cradle to Grave.
