Offering further proof that GOP presidential candidate Herman Cain has inappropriately touched a national nerve, Tim Heidecker has debuted Cainthology (Songs In The Key Of Cain), a nine-song musical ode to the man who long ago invited everyone aboard the “Cain Train” before that started to sound dirty and unfortunate. As you may recall, Heidecker was one of the first to grab a seat, creating his own “Cain Train” video shortly after the Cain campaign paid unwitting tribute to Tim And Eric’s hypnotically awkward amateurishness with its creepy video of Mark Block having a smoke while Cain smiled as he imagined all the ways he’d like to offer you a job, baby.
