Cameron and Mitchell take Lily to get her first picture with Santa and the mall.  When it's their turn, the good Santa goes off, and some homeless Santa that looks nothing like him goes up.  They complain and get him fired and run into the Santa in the parking lot.  Overriden with guilt, when they find out he's going to spend Christmas in his car, they invite him to their place.  They come close to admitting they got him fired, but it turns out Santa Scott knew and forgave them after how nice they were to him.  When a the choir group that Cameron formed and was fired from shows up to sing, Cameron wants to turns the sprinklers on them, but Santa Scott convinces him to be nice in the holiday spirit.  Cameron goes outside and when the new choir master insults him, Santa Scott knocks him out and takes off running.  Classic.
