You see, the Twids used to take their produce to the other side of the mountain to sell at market. It would have only taken a couple of hours if they could go over the mountain, but he giant would not suffer them to pass. So they had to go the long way, requiring three days to get to market, sell their produce, and get back. Occasionally a delegation of Twids would go to the top of the mountain to beg the giant to grant them passage, but he would just roar and kick them all back down the mountain.
One day a visiting Rabbi heard their tale of woe and said, "I have had success in the past negotiating with otherwise intractable characters. Perhaps I could accompany you and help this Giant to see a better path." The Twids agreed it was worth the try, so the next morning they dutifully headed up the mountain. When they reached the top, the Rabbi stepped forward and called out to the giant, saying, "Mr. Giant, I am a visiting Rabbi, and I have come to speak to you on behalf of these fine Twids." No sooner were these words out of his mouth when the giant roared out and kicked all the Twids down the mountain. But he did not touch the Rabbi.
When he was finished, the Rabbi asked him, "Mr. Giant, why did you kick the Twids down the mountain but leave me untouched?"
The Giant replied, "Silly Rabbi, kicks are for Twids!"
