From the BBC: (thanks, Mungo Says Bah!)

The poem appeared in a Burmese celebrity gossip magazine

The Burmese authorities have arrested a well known poet, who published a love poem with a hidden message criticising the country's military leader.

Poet Saw Wai's work - titled February the Fourteenth - was published in a Rangoon magazine, The Love Journal.

Taken together, the first words of each line read: "General Than Shwe is crazy with power."

Dissidents in Burma have used similar techniques before to get their messages past government censors. ...

Last year an advertisement was placed in one of Burma's main newspapers in the name of a Swedish travel company which contained the hidden message "Killer Than Shwe".

The company did not really exist.
