Famous quotes containing the words counterfeit and/or pen:
“I can counterfeit the deep tragedian,
Speak, and look back, and pry on every side,
Tremble and start at wagging of a straw,
Intending deep suspicion. Ghastly looks
Are at my service like enforced smiles,
And both are ready in their offices
At any time to grace my stratagems.”
—William Shakespeare (1564–1616)
“Its whether will ye be a rank robber’s wife,
Or will ye die by my wee pen knife?
Its I’ll not be a rank robber’s wife,
But I’ll rather die by your wee pen knife.
He ‘s killed this may and he ‘s laid her by,
For to bear the red rose company.”
—Unknown. Babylon; or, The Bonnie Banks o’ Fordie (l. 9–14)
