When I referred to knights as weird, I was thinking more of how their movement patterns are incongruous with rooks/bishops/queens that move in a straight line but are blocked by pieces in the way. Their weirdness is what makes them useful (uniqueness may have been a better word). I liked the way another commenter described it below: knights can move to the closest squares other pieces can't move to.
