Three priests passed every day through a street that led them from Church to a Sanctuary. They noticed a parrot that stood at the entrance of a Sanctuary. Every time they passed in front of that building, the bird would pronounce three sequential colors. One day, they heard, "whitey, whitey, tighty."

One of the priests noticed that those colors perfectly matched the colors of their underwear. He mentioned his discovery to the other two priests, but both were reluctant to believe that could be possible. The next day, they all wore black underwear and passed in front of the house, and very precisely the parrot spoke, "blacky, blacky, tighty."

Hearing that, the three priests were astonished! One of the priests spoke up, "Gentlemen, tomorrow we are going to trick that bird."

Saying that, He recommended that the next day, none of them should be wearing any underwear under their garments. Respecting their agreement, the next day they wore no underwear, and proceeded to pass in front of the parrot's house. They looked at the bird. At the beginning, the parrot looked a bit puzzled, he swung back and forth on the branch he was perched on. Then, after a while, the Parrot said, "Straight, Straight, Gay!"
