Muller also co-starred with his brother, Mark, in the reality TV series God, Guns & Automobiles, which aired on History Channel.

[2] Erich Muller worked as a model and child actor, appearing in regional print and television commercials as well as Kansas City theater productions.

[3] As a youth he appeared in over 100 stage performances, with one notable long-running role being that of Billy Ray Jr. in the play On Golden Pond.

In his book Dad, Dames, Demons, and a Dwarf: My Trip Down Freedom Road, he recounts an incident in fifth grade where, in an act of corporal punishment, he was severely beaten with a board by the school principal, an event that changed his outlook on organized religion.

[4] At CMSU he continued to work in theater, and it was his role as a half-man, half-beast in one production that gave rise to his nickname "Mancow".

He got a job at KOKO in Warrensburg as a late night control board operator, playing local commercials during satellite broadcasts of The Larry King Show.

Among Muller's fans was the general manager of KLSI-FM, Kansas City, who offered him a full-time job as head of station promotions.

Muller accepted the position, plus a weekend air shift, while completing his final semester at Central Missouri State.

After graduating in 1990, Muller was hired as the morning drive air talent at Kansas City's KBEQ-FM, Q-104, where the Holy Moley & Maxx Show quickly rose to #1 in the ratings and helped Q-104 dominate the market.

Now going by his old college nickname Mancow, in 1993 Muller made national headlines with a publicity stunt that caused a major traffic problem for San Francisco.

Reacting to a subsequently debunked story that President Bill Clinton had tied up air traffic at Los Angeles International Airport for over an hour while getting a haircut from celebrity hairstylist Cristophe aboard Air Force One, Muller staged a parody of the incident on the San Francisco–Oakland Bay Bridge during rush hour.

The radio station settled a civil suit by paying $1.5 million, including $500,000 to cover three toll-free days on the bridge.

[5][6] Muller accepted a job offer by Evergreen Media President Jim de Castro at more than double his salary to move to Chicago and work at "Rock 103.5" (WRCX).

Muller's Mancow's Morning Madhouse ended its live run on Emmis' Alternative outlet in Spring 2006, and had the highest rated audience in Chicago with men ages 25 to 54 (among English speaking stations).

According to the Arbitron radio ratings service, Mancow's show, measured in Average Quarter Hour listening percentages (AQH) had a 5.7 share.

[10] Between 1999 and 2004, David Edward Smith's Citizens for Community Values filed 66 indecency complaints with the FCC relating to Muller's program, leading to 6 citations and $42,000 in fines.

Durst was eventually sued for breach of contract (for not completing the show) by Chicago lawyer Michael Young in a class-action suit.

The talk show host had previously claimed that calling waterboarding "torture" was wrong, something he had stated that he hoped his reenactment would prove.

South had no formal training in waterboarding and had never before performed the procedure, leading the online celebrity and gossip site Gawker to accuse Muller of faking the whole thing.

The event deeply affected Muller and in part prompted him to write his first book, Dad, Dames, Demons and a Dwarf.
