The President has a tip for those who want to learn how to separate his jokes from his serious statements.
"Look at my eyes," President Duterte said.
Duterte admitted that he sometimes plays with the media.
"Nilalaro ko kayo. Mahilig talaga ako sa ganoon. Alam ng team ninyo. Mahilig talaga ako magbitaw ng kalokohan," Duterte said.
"Istorya lang naman iyan. Maniwala pa kayo?" he added.
Duterte during the campaign bragged about riding a jetski to the disputed islands in the South China Sea and plant the Philippine flag on Scarborough Shoal.
He later said that it wasn't a serious statement, saying he didn't even know how to swim.
