KETCHUPNMUSTARD is one of the many hit songs on Kill Harbert's award winning 2008 EP, "5th Grade Living Museum." It was inspired by a real life event at Green Oaks Fundamental Elementary School when fellow classmate, Zavien, tried jumping over a desk in 4th grade and tripped, tearing open his leg, to which fellow classmate, John Paul, exclaimed, "It looks like ketchup and mustard!"
