Deputy Columbus Duncan is a deputy in Jefferson County, Missouri. In a more recent date, he has become a Canine Deputy for the Jefferson County, Missouri Sheriff's Office. The soundboard played a part in the A Nightmare On Burton Street prank-call series. It remains unknown as to his origin, but his soundboard is often used in prank calls, but not in the frequency as Deputy Martin. Deputy Martin's soundboard is often used to throw the victim off course and convince them that the caller is actually someone who is on the victim's side and is trying to investigate the prank. This, when used in conjunction with a more aggressive soundboard, such as the Satanic Racist or Tom the Pissed Off Roofer, can cause large amounts of confusion on the part of the victim. The call in which he was found is considered lost, however it is thought that a Deputy Martin soundboard was used during the call, considering he said something about Big Daddy's Pizza and knowing of a Deputy Martin.
The original call to Deputy Duncan has been identified as being in a prank called 'Dennis the Drunk vs. The Cops', made MrNismo88 and Prankforever2K9, in which the good lawman converses with Rick the Mulletman and then gets called back by Deputy Martin. On August 5, 2013, the call was re-uploaded by TheZodiacz.
