Selling many bibles

Three little boys were looking for a summer job. Their preacher needed some
people to go around and sell bibles. So the preacher hired two boys without
even thinking twice. But he was hesitant about hiring the third boy because
he suffered from a speech impediment.

So after the first days of work they all met back at the church. The
preacher looked at the first boy and asked him, "How many bibles did you
sell?"

The boy stood up and said, "35."

"Is that all you sold?" the preacher asked.

"He looked at the second boy and asked him the same thing. The boy said,
"75." "That is good," the preacher replied.

He didn't want to ask the third boy but did. The boy with the speech
impediment said ''I-I-I s-s-sold 175.'' The preacher was amazed and asked
the boy how did he sell all of the bibles. He said ''I-I-I t-t-told them to
b-b-buy t-t-them or I will r-r-read it to t-t-them'''
