Famous quotes containing the words packet and/or structure:
“The captain was a duck
With a packet on his back,
And when the ship began to move
The captain said, Quack! Quack!”

“When a house is tottering to its fall,
The strain lies heaviest on the weakest part,
One tiny crack throughout the structure spreads,
And its own weight soon brings it toppling down.”
—Ovid (Publius Ovidius Naso)
