The lyrics sound to me like they'd cause someone to become utterly obsessed with tacos for the duration of the song. The question is, does the song affect Doug, a single chosen target, multiple chosen targets, everyone within Doug's area of effect except for Doug or everyone within Doug's area of effect including Doug?
