1. I believe in an immortal soul, so any blind dude who'se busted his brain enough to lose his sense of taste fits the first riddle.

2. A circle? I guess a rounded side is strill a side, but it's haed to tell when the side begins and ends. So I'll say one. I'll also steal the "inside" answer.
So a circle would have 2 sides. Or else it's an incalculable number.

3. Up the chimney down but not down the chimney up?
That's a trick question. The answer is trickier: Santa Claus (Happily, I don't have to justify this because I'm obviously right)
