Philippines President Rodrigo Duterte is often in the news thanks to his frequent outbursts which are filled with cuss words, expletives and open threats. However, he has now decided to mend his ways after he promised God that he will not use bad words again.

The controversial foul-mouthed leader who once called the pope a 'son of a bitch' and told Barack Obama to 'go to hell', made the announcement in the southern hometown of Davao city late Thursday after he came from his trip to Japan.

He said that while he was travelling in the plane, he heard a 'voice' which threatened him that if he doesn't stop using cuss words, the plane will be brought down.

"And I said, `Who is this?' So, of course, it's God. So, I promise God to ... not express slang, cuss words and everything. So you guys hear me right always because (a) promise to God is a promise to the Filipino people," he said, reports Associated Press. 

Duterte's bizarre stance against drug trade is also well known as he openly threatens kill drug dealers in Philippines. Recently,  he appeared to liken himself to Nazi leader Adolf Hitler and said he would "be happy" to exterminate three million drug users and peddlers in the country.

"There are three million drug addicts (in the Philippines). I'd be happy to slaughter them. If Germany had Hitler, the Philippines would have...," he had said, pointing to himself, reports AFP.
