(Better Quality REUPLOAD) Disney's Teacher's Pet Episode Six Part Two - S01E06B - Costume Pity Party

On Halloween day, Leonard explains that he doesn't wear costumes anymore for the season since someone had bullied him the previous year (It's later found out that said bully was made fun of previously for wearing a disco costume the year prior to that). In the meantime, Spot's cover nearly is blown when his costume falls apart and appears as his actual self as he arrives at school, but everyone believes that he's actually in costume as a dog, so he goes with it and pretends to be Scott in a dog costume, but things go awry when they are told to take off their costumes for later.
