If you've seen the old John Wayne / John Ford movie Donovan's Reef, the lyrics are given "the monkeys have no tails in Zamboanga." I haven't been to Pago Pago, but I have been to Zamboanga, and I did meet a tail-less monkey near there. He belonged to a Catholic priest, who had his collar attached to a steel ring that ran along a cable, so the thing could climb up and down the church.
Nice guy. Pretty brave ministry, there in the Autonomous Region in Muslim Mindanao. But most of the Republic of the Philippines' special ops guys are Catholics.
