For their performance of the song "Mule Train," it has become an Illbilly tradition to invite an audience member onstage, who is presented with a JB-crafted device that mimics the sound of a whipcrack, then instructed to operate this device energetically each time JB yells, "YAAAH!" This member of the Hannah-karaoke duo was hard to miss in her shiny Hannah-oriented jacket, and was chosen for this honor.
Amazingly, no audience participant has yet slapped their own nose in the slapping device. But one can always hope.
