MACDUFF
Was it so late, friend, ere you went to bed
That you do lie so late?

PORTER
Faith, sir, we were carousing till the second cock, and drink, sir, is a great provoker of three things.

MACDUFF
What three things does drink especially provoke?

PORTER
Marry, sir, nose-painting, sleep, and urine.
Lechery, sir, it provokes and unprovokes. It provokes the desire, but it takes away the performance.
Therefore much drink may be said to be an equivocator with lechery. It makes him, and it mars him; it sets him on, and it takes him off; it persuades him and disheartens him; makes him stand to and not stand to; in conclusion, equivocates him in a sleep and, giving him the lie, leaves him.

MACDUFF
I believe drink gave thee the lie last night.
