In Praise of Big M

The news that a US couple is suing McDonald's, because nude images of the wife ended up on the Internet (don't ask), made me look again at the big M. It's a variant of subliminal advertising. The golden arches are breasts. All they need are nipples on top to make their meaning obvious. And what do breasts mean to us? Mother's milk nurturing our young, trustworthy, safe, sexy and universal. What artistic genius created this maternal symbol to persuade the world's teenagers to eat beefburgers with a squirt of ketchup, a lick of cheese and a slice of gherkin?
