i think thats all there is to it
here goes the story
1-theres this doctor, he put an add in the news paper stating he will pay 10000$ for a left arm.
2-first guy applied, doctor looked at his arm and said no
3-second guy applied, doctor looked at his arm and said no
4-third guy applied, doctor looked at his arm and said no
5-fourth guy applied, doctor looked at his arm and said no
6-fifth guy applied, doctor looked at his arm and said ok
7-the doc cut his arm off, and paid the fifth guy 10000$
8-the doc then wrapped up the arm and sent it to person 1
9-person 1 looked at it and said ok and packed it together and sent it to person 2
10- person 2 looked at it and said ok and packed it together and sent it to person 3
11-person 3 looked at it and said ok and packed it together and sent it to person 4
12-person 4 looked at it and said ok and packed it together and sent it to person 5
13-person 5 looked at it and said ok and buried it in his back yard
basically the question is why did the doc send the arm to the ppl, and why did the 5th person bury the arm
