`` Not a bit of it ! '' shouted BOB , ceasing his Terpsichoreanism for a moment ; `` do n't you see the joke ? It 's all in the looking-glass , my pet . When I thought it was a quarter past Twelve and fled the residence , it was really a quarter _ of _ Twelve -- do n't you see ? The looking-glass _ reversed the hands on the watch _ ! '' And so it was , _ mon ami _ . Hold your own time-piece with its face to a mirror , and you will `` see the point . ''
