Eggs. Ever Heard of Em'?

Apparently Leo Burnett of Chicago has concocted this advertisement near the McDonalds at Clark and Addison. Here's my question: Since when did anyone need to advertise for EGGS. We all know about them, women ovulate them, kids use em' to throw at cars, my grandma bakes with em', and chickens lay em'. We don't need some big ass billboard to tell us eggs are around and we can eat em' if we want. EVERYONE IS AWARE OF THE MCGRIDDLE! GOD LOVE THE MCGRIDDLE. I don't need anyone to remind me that McDonalds has eggs.
