On this episode, Ethan plays music that requires knocking on the piano. First, he plays the historically important Carolina Fox Trot, which has some clapping and knocking, and was actually the first published Fox Trot ever. Then, Ethan plays an original composition called the "Whack-a-Mole Rag" in which he tries to whack pesky musical moles. Finally, soprano Melinda Whittington pops in, gives Ethan some hair-care advice, and sings "Knock Wood" with a little percussion solo.  

Gina Marie is back to sing songs about true crime. Hear the titillating story and song about Aaron Harris, the New Orleans serial killer who used voodoo magic to stay out of jail. Then, hear Gina sing "Stagger Lee," the song about an old St Louis murder. To lighten things up, Ethan creates a new song about a real Chinese criminal named Cai who painted a new lane on the road in order to ease traffic, but was caught and fined $151. Finally, Gina wails the most famous murder ballad of all time: "Frankie and Johnny."
