What! Man has still not mastered the art of walking and you folks think they can fly
For the most part, man has mastered the art of walking... it's just those who imbibe rather heavily who have difficulty. You know, one step forward and three steps back... and detours both left and right while the intoxicated diligently seek an imaginary line they're supposed to follow in order to get home.
Anyhow, if God intended that man should fly, he'd have given us all Leer Jets.
