A farmer and his son, traveling by horse and buggy up a narrow lane, met a motorist going the other way. There was no room to pass for two miles in either direction. The motorist, in a hurry, honked his horn.
"If you don't back up," said the farmer, rolling up his sleeves, "I won't like what I'm going to have to do." The surprised driver put his car in reverse and backed up two miles, allowing the horse and buggy to go by.
"What was it you wouldn't have liked to have done back there?" asked the farmer's son.
"Back up two miles," replied the farmer.
