Famous quotes containing the word trunk:
“Let me have
A dram of poison, such soon-speeding gear
As will disperse itself through all the veins
That the life-weary taker may fall dead,
And that the trunk may be discharged of breath
As violently as hasty powder fired
Doth hurry from the fatal cannon’s womb.”
—William Shakespeare (1564–1616)
