In the year 1740, the members of a drinking club had a negro boy attending them who used to mimic people for their amusement. The men bid him mimic Mr. Whitefield, which he was very unwilling to do; but they insisting upon it, he stood up and said, "I speak the truth in Christ, I lie not; unless you repent, you will all be damned.”
Through this unexpected speech, the club was entirely broken up.
