When Iranian President Mahmoud Ahmadinejad got an anonymous text message suggesting he didn't wash enough, he did not take it lying down.

He fired the president of the phone company, had four people arrested, took other legal action and accused those involve of conspiring with the Israeli foreign intelligence service Mossad, according to the Iranian opposition website Rooz Online.

The website says Ahmadinejad, known throughout the world as a hard-liner who has threatened Israel with destruction and questioned the Holocaust, is the target of many barbs among the populace in his country.

But the mullah regime doesn't show much of a sense of humor. Of particular concern are jokes comparing Iran's nuclear ambitions with sex. Several people have reportedly received court summonses for sending nuclear-related jokes, according to the website.

Tehran has taken a tough stance against opposition on the Internet. Many of the nation's estimated 70,000 to 100,000 bloggers have faced harassment or imprisonment. The regime has acknowledged monitoring text message traffic.
