There exist two, and only two, of these items in the world. One of which is possessed by a cranky and lonely half-orc. It appears to be an innocuous wooden banana with a coat of faded yellow paint. When an end (doesn't matter which one) is placed against your ear, you can hear a ringing followed by a click and a half-orc yelling at you for waking him up at this ungodly hour. If you drop the banana or "hang up," the call ends. If you stay and listen, the half-orc will yell at you, call out obscenities, and start going on about his daily problems and mishaps in his love life. Every so often (2% chance/day), the banana will ring while you are sleeping and the half-orc will want to talk to you about his problems.
Wondrous Item, varies
