Chet the signing parrot

One Christmas Eve, a frenzied young man ran into a pet shop looking
for an unusual Christmas gift for his wife. The shop owner suggested
a parrot, named Chet, which could sing famous Christmas carols. This
seemed like the perfect gift. "How do I get him to sing?" The young
man asked, excitedly. "Simply hold a lighted match directly under his
feet." was the shop owner's reply. The shop owner held a lighted
match under the parrot's left foot. Chet began to sing: "Jingle
Bells! Jingle Bells! ..." The shop owner then held another match
under the parrot's right foot. Then Chet's tune changed, and the air
was filled with: "Silent Night, Holy Night..." The young man was so
impressed that he paid the shop-keeper and ran home as quickly as he
could with Chet under his arm. When the wife saw her gift she was
overwhelmed. "How beautiful!" She exclaimed, "Can he talk?" "No," the
young man replied, "But he can sing. Let me show you." So the young
man whipped out his lighter and placed it under Chet's left foot, as
the shop-keeper had shown him, and Chet crooned: "Jingle Bells!
Jingle bells!..." The man then moved the lighter to Chet's right
foot, and out came: "Silent Night, Holy night..." The wife, her face
filled with curiosity, then asked, "What if we hold the lighter
between his legs?" The man did not know. "Let's try it," he answered,
eager to please his wife. So they held the lighter between Chet's
legs. Chet twisted his face, cleared his throat, and the little
parrot sang out loudly like it was the performance of his life:
"Chet's nuts roasting on an open fire...."
