Ahmadinejad's Letter To Bush

An acquaintance of mine who works for the National Censor's Bureau was telling me the other day that they actually had to cut out a part of Ahmadinejad's much-publicized letter to Bush for security reasons before they released it to the press, because they simply couldn't figure out what it meant. The part was actually a one-liner and came in the form of a post-scriptum at the end of the letter. It said:
"p.s. Mr. President, if you don't forward this letter to 20 other people immediately, you will have 20 years of bad luck."
