My name is Lizard Eater and I am a Silly Fun Addict . Even more fun than the movie : my 77 year old mother had so much fun ; I burned her a copy of the soundtrack which she has apparently been playing every morning as she fixes her coffee . * Then I made her a copy of ABBA greatest hits , which she is also playing obsessively . My mother is Very Dignified , so to see her letting her hair down is quite enjoyable .
