During his brief time as a star among America's socially-aware stand-up comedians of the late 1950s and early 1960s, Brother Dave successfully fused a stream-of-consciousness style of addressing subjects (e.g., Lord Buckley, Jean Shepherd) with a classic Southern 'storyteller/liars'-bench' manner (e.g., Andy Griffith, and the later Justin Wilson and Jerry Clower), setting himself apart a bit from Northern Jewish contemporaries such as Mort Sahl, Lenny Bruce, and Shelley Berman. His "stream of consciousness" style got him in trouble in 1963 when he was booked by Baylor University student Rod Phelps to perform on campus. His line that went something like "I was in World War Two and I saw lots of blood spilled but it never sent anyone to Heaven" caused the audience to leave in droves. The Baylor President called Phelps into his office the next day and handed Rod a handful of telegrams complaining about Gardner's performance. Phelps had to write each sender and apologize for the remark. He had succeeded in getting Baylor to book Brother Dave because Gardner's uncle was a pastor who had developed the Sunday evening "Training Union" program then widely used in Southern Baptist churches.
