True story:
-- December 25, 1972. About midnight local time.
-- Somewhere off the Chinese coast on patrol in the Amercian submarine USS Pintado (SSN 672) on a special operation
-- The players:
Conn -- The conning officer (officer of the deck)
Sonar -- The boat's underwater ears
ESM -- Electronic Support Measures; the people who detect radar emissions
Radio -- The radio room, temporarily taken over by some mysterious sailors, including a much younger version of Llarry; few crew members know what they do.

On the intercom, which all parties can hear, between the above players:

"Conn, this is sonar; I have detected a faint jingling noise, bearing directly North."

"Conn, this is ESM. I have sleigh type emissions also bearing directly North."

"Conn, this is radio. I have faint "Ho, ho, hos!" on VHF."

"All, this is conn, Thank you and Merry Christmas, guys!"
