Nanny enjoys food and drink despite only having one remaining tooth (the sight of Nanny Ogg eating a pickled onion is described as bringing tears to the eyes). When she is drunk, she has a tendency to sing very "special" songs, the most popular being "The Hedgehog Can Never Be Buggered At All" or simply "The Hedgehog Song" (never really unveiled by the author beyond a few lines, but many readers have written their own versions). A close runner up for the most popular Nanny Ogg song is "A Wizard's Staff has a Knob on the End", a version of which has been written by Heather Wood, with music by Dave Greenslade. It is also notable that Nanny Ogg once gave Agnes Nitt lessons on how to sing, including how sing in harmony with herself (using her alter ego, Perdita).
