Good for them. They have it there anyway. Put a price on it and lay a couple pieces that look nothing like the picture on there.
I'll betcha down my Pittsburgh (where the Big Mac was invented if you remember), they are coming up with a way to add fries to their Mickey D's, ala Primanti Bros. sandwiches.
Give us this day our daily bacon.
