The bumble bee doesn't know that, aerodynamically, it shouldn't be able to fly. So it goes on flying anyway. When I was 4, I didn't know that, according to gravity and the incompatibility of circular surfaces on a corrugated plane, I shouldn't ride my bike down the stairs. So I got stitches anyway.

The point:

DON'T be stupid, but DO defy the odds.
