Terry Pratchett said this quote
“ And one day Amber takes her troll’s dinner down to the cave and finds him—” Rock waved his hands in vague yet thoroughly descriptive motions “—with another lady troll. So she go home and get her club and come back and beat him to death, thump, thump, thump. ’Cos he was her troll and he done her wrong. Is very romantic song. ”
