Under the alias Roy D. Mercer, Douglas lured unsuspecting folks into his world of hilariously absurd phone calls, armed with a thick Southern drawl, outlandish fake complaints, and a knack for tossing in the occasional off-color quip—all topped off with a comically menacing promise to settle it in the parking lot.
The Mercer character became known for catchphrases like “How big a boy are you?” and “How would you like an ass-whooping?”
RIP Brent Douglas (Roy D. Mercer).

The Roy D. Mercer character was born on KMOD, where radio hosts Douglas and Phil Stone entertained listeners for nearly three decades. The segment’s popularity soared, leading them to compile a collection of prank calls onto a CD, which they released locally in 1994.

Per NPR affiliate KOSU, country music producer Scott Hendricks signed the act, leading to the release of over 20 Roy D. Mercer prank call comedy albums between 1996 and 2013. The character’s popularity inspired the creation of a song and music video titled “How Big’A Boy Are You.” It featured vocals by the legendary Charlie Daniels.
Stone passed away shortly after the duo departed KMOD in 2012, marking the end of their era of prank calls as well.
