A fictional radio character created by Brent Douglas and Phil Stone for their morning radio show on KMOD-FM in Tulsa, Oklahoma. Douglas would assume the character by donning a mushy fake Southern accent, and call up someone (either a random businessman or, even in a few cases, a celebrity), usually claiming that they pay for some perceived wrong or receive an "ass whoopin'". Most of the victims were suggested to Brent and Phil by friends, who would often provide information to make the pranks more believeable. Near the end of each call, Roy would usually name-drop someone that the victim knew as a means of letting on that the call was a prank.
In addition to playing the calls on their radio show, Brent and Phil released 12 albums of Roy D. Mercer calls for Virgin Records and Capitol Records between 1997 and 2013. The first seven albums were titled How Big 'a Boy Are Ya? volumes 1-7, but they broke away from the theming with Roy D. Mercer Vs. Yankees in 2001, Roy D. Mercer Hits the Road in 2003, Get Well Soon in 2004, Black & Blue in 2006, and Red, White & Bruised in 2013, along with eight random compilations. Their radio show ended on October 12, 2012, one month before Phil died of heart disease.
Tropes present in Roy's work:
- Candid Camera Prank: The purpose of their prank calls is to wind up the target for comedy's sake.
- Catchphrase: "How big a boy are ya?"
- Celebrity Cameo: On one album, he prank-calls Goldberg.
- Chronological Album Title: The first seven albums were just titled How Big a Boy Are Ya? Vol. 1 through Vol. 7, after which they Stopped Numbering Sequels.
- Deep South: Roy is portrayed as a none-too-intelligent hick with an equally hick-ish wife named Sharon Jean, a son named Raymond, and a dog named Bon Jovi.
- Oddly enough, the daughter's name is Latisha, which isn't what you'd consider a stereotypically southern name.
- Expy: Many people have pointed out that his shtick was very similar to "Leroy Mercer", a prank call sketch created in The 80s by a Tennesseean named John Bean, who also threatened people with "ass-whoppin'"s.
- In and Out of Character: Douglas sometimes broke character and spoke in his normal voice when revealing the prank.
- Prank Call: The entire point of the show.
- The Reveal: Usually done by name-dropping a friend of the victim.
- Something Completely Different:
- Vol. 2 ended with a parody of 'Twas the Night Before Christmas titled "Mercer Family Christmas".
- Vol. 3 ended with a "Jingle Bells" parody called "Jingle Fists".
- Vol. 4 and Vol. 5 had tracks that were just topical conversations between Roy and Phil Stone set to fiddle music (five on the former, four on the latter.)
- Vol. 6 ended with a musical track, consisting of a phone call interspersed with backing music and a chorus sung by Charlie Daniels (produced by Scott Rouse, who did similar "remixes" with standup material by Jeff Foxworthy and Bill Engvall). This was also made into a music video.
- Vol. 7 ended with a skit where Roy competed on Who Wants to Be a Millionaire?, with a friend of theirs taking the role of then-host Regis Philbin. Roy uses all three of his Lifelines and still gets the $100 question wrong before beating up Regis.
- On Hits the Road, several tracks feature 30-second intros, and the last track is a skit called "I Believe" set to mandolin music.
- Red, White, and Bruised has four political messages and another track that has a call set to banjo music.
- Vol. 6, Hits the Road, and Get Well Soon all have tracks intended to be used by listeners as answering machine messages.
- Stopped Numbering Sequels: After Vol. 7, the albums broke free of the numbering scheme.
- Strictly Formula: See above.
