And back in the day there was Charo (of the coochi-coochi schtick) who was married to the goaty old bandleader Xaviar Cugat. But, you know, like Beauty and the Beast, it's a song as old as time.
Obviously though Shakespeare is talking about something slightly different. Here neither lover is a prize, or at least both are too old and worldly (in a bad way) for love to be a sweet or faithful thing. But both take consolation in mutually recognized lies to the contrary. However false, says Shakespeare, the illusion of a better intimacy is one of love's best tricks.
The poem's sophisticated, candid tone reminds me of Catullus. Its structure (not its form, which is obviously a sonnet) reminds me of Martial (who was highly influenced by Catullus). Martial would introduce an irony or contradiction (sometimes a shocking one), ask how it could be, and respond with an urbane, often cynical resolution. I think Shakespeare knew both of these Latin poets.
