Quite a few of the original Furnace Fun answers were very borderline but considering each play you get a random mix of answers I imagine it was easier to hide. I can't specifically recall one exact favourite but the concept itself was brilliantly done. I do remember Banjo's shocked cries of "Kazooie!" being a highlight of my childhood, even though I didn't quite understand why at the time.
