A sergeant entered a pet shop. "We need a talking parrot as a unit mascot."
"Talking parrots have been sold out," informed the salesman. "I see from your
branch insignia you're from the signal unit?"
"Yes," replied the sergeant.
"Then I could suggest a wood pecker."
"Can the wood pecker talk?"
"In a way. He is very well qualified as a Morse code operator."
