Trump-bashing “comedian” Seth Meyers went to his go-to source for jokes by making fun of the matching hats Japanese Prime Minister Shinzo Abe presented to President Trump over the weekend.

During his show on Monday, Meyers said that Trump’s trip got off to a “rough start” when he flew to Hawaii, where former President Obama was born.

“Trump’s motorcade was greeted with protesters lining the streets, reminding him of his past as a birther, with signs like this one that said: ‘Aloha POTUS, welcome to Kenya,'” Meyers quipped. “There’s a good chance he saw that sign and thought he was actually in Kenya.”

Meyers went on to make fun of Trump’s arrival in Japan, where Abe presented the president with a hat that said in gold writing: “Donald & Shinzo, Make Alliance Even Greater.”

“Abe is a smart man. He figured out the only way to communicate effectively with Donald Trump is via [a] hat,” Meyers said.

The show host then reached over and pulled out a white hat of his own, sporting gold writing that said: “Resign Donald.”

Meyers said the words on the hat presented to Trump “sounds like what you say to a monkey if you were teaching it sign language,” he mocked. “Human and ape make friendship stronger.”

Trump kicked off his 12-day Asia-Pacific tour to meet with regional leaders from five countries, arriving at his first stop in Japan on Sunday.

The president is looking to present a united front with the Japanese against North Korea in the wake of Pyongyang’s defiant nuclear and missile tests.

During his visit, Trump and Japanese Prime Minister Shinzo Abe met with the families of Japanese citizens abducted by North Korea.

Trump’s tour of Asia will be the longest by an American president since George H.W. Bush in 1992. Besides Japan, he plans to visit South Korea, China, Vietnam and the Philippines. He will be joined by First Lady Melania Trump for part of the trip.
