There was an old man of Tarentum,
Who gnashed his false teeth till he bent 'em:
And when asked for the cost
Of what he had lost,
Said, "I really can't tell for I rent 'em!"
—Gilbert K. Chesterton.
Pat came to the office with his jaw very much swollen from a tooth he desired to have pulled. But when the suffering son of Erin got into the dentist's chair and saw the gleaming pair of forceps approaching his face, he positively refused to open his mouth.
The dentist quietly told his office boy to prick his patient with a pin, and when Pat opened his mouth to yell the dentist seized the tooth, and out it came.
"It didn't hurt as much as you expected it would, did it?" the dentist asked smiling.
