Talkers Magazine February issue 1999-2000-2001 Prell earned a dedicated audience for his outspoken liberal views and sarcastic debates with callers who disagreed with him.
His caustic one-liners and humorous hang ups were considered daring at the time, but are now commonly replicated by more conservative talk show personalities like Mark Levin.
He was arrested and briefly jailed for trespassing to photograph the infamous local brothel, The Mustang Bridge Ranch.
Other stations Prell hosted call-in programs on included: WTOP Washington; WEEL Fairfax, VA (also program director), where he hosted the midday Party Line and Date Line call-in shows; WLMD (now WACA) Laurel, MD; WRNG Atlanta; KIRO Seattle; and WBAL Baltimore (where he worked for 17 years).
His character was the inspiration for the call-in parody series, The Papa Prell Show, which aired on college radio stations from 1983 to 1994.
