" Poetic simile was strictly limited to statements like 'his mighty steed was as fleet as the wind on a fairly calm day, say about Force Three,' and any loose talk about a beloved having a face that launched a thousand ships would have to be backed by evidence that the object of desire did indeed look like a bottle of champagne. "

― Terry Pratchett , The Light Fantastic (Discworld, #2; Rincewind #2)
