Kevin Ahern's Metabolic Melodies, Verses & Mildly Popular Limericks [Link]

Hours of goodness on Kevin Ahern's site - music, limericks & poems, if such things take your fancy.  Videos like this make me think I would have loved to learn stuff such as Gluconeogenesis if a teacher had made it as interesting! :) Who says education, music & fun can't go together?
