I think up of a new joke recently! it goes like this:

One day, a man named jerry, wanted to go to Mars to live for 1 month. So, it means that he can only return to Earth after 1 month. Thus, he had to bring sufficient foods for his stay. He brought 100 boxes of food to Mars. When he reached, a Martian asked Jerry, " hi tourist! Do u wan to exchange all ur food for 100 packs of cigar? " Being somebody who was a smoke addict, Jerry immediately agreed, as he slipped his mind of bringing any cigar to Pluto.
The Martian said that he nid 1 week to bring the 100 packs of cigar to Jerry, by using a land rover. Jerry, being a clever man, marauding for ideas to have both food and cigar. So, he thought," hmm, the Martian nid to use a land rover to bring the cigar to me. If i does'nt have any food for the exchange, he also cannot be able to bring bak the cigar, as the rover would not have sufficient petrol." Thus, Jerry ate up all the food during the 1 week. When the Martian return with the cigar, he saw that all the food had been eaten up. He was filled with apoplexy. No chioce for him, the Martian gave Jerry all the cigar. Jerry drew out 1 cigar, then asked the Martian," hey! May i borrow a lighter?" the Martian answered," sorry sir, i sell cigar only, and i does not provide lighter for my customers."
Jerry: wat the...! Then how do i smoke!
(You guys will know wat happen next right?) LOL!!!
