B is for BAD
Its not even really insulting to canadians.
Its just a bad song, accompanied with mediocre flash. Creative liscence is basically making an animation for whatever he says in the song.. real original. Go watch Adam Phillips' flashes for a minute and you'll know what real flash is.
Check out Maxwell's silver hammer, and you'll find that a song like that is open to literal or metaphorical interpretations.
Weird al + lack of creativity = bad flash.
