Plot summary
Murderface's birthday party is approaching and the rest of the band cannot decide what to get him. They initially present him with the darkest, most brutal gift of all: nothing. They go to a castle to meet Margrethe II of Denmark (voiced by Metallica 's Kirk Hammett ). She is later killed after sampling the mercury frosting of Murderface's cake. After he storms out, the band gets him the car that John F. Kennedy was assassinated in, outfitted with other various brutal historic items (most notably, the theater chair that Abraham Lincoln was sitting in when he was assassinated, installed in place of the driver's seat) and enrolls him in a "Dethderby" to demolish other cars so he can literally "destroy United States history." Dr. Rockso makes his debut appearance. Guest voices: James Hetfield and Kirk Hammett of Metallica Songs included: "Birthday Dethday"
