Last Shabbat I related something to my rabbi which I noticed several years ago. Whenever we learn about the Ketoret (the incense) I remember a fact that Kentucky Fried Chicken (KFC) used to advertise that the special recipe used by the 'Kernel' involved 11 herbs and spices which coincidentally is the number of spices in the Holy Incense.
I always wonder if the #11 was chosen because of this...
