No. 132 - Big Mac

I had two Big Macs for lunch, with fries, and a sweet tea. It hit the spot.

I learned that the Big Mac was invented in the late 1960s by a Pittsburgh, Pennsylvania franchisee who designed it to compete with a similar Big Boy sandwich. I also learned that the "secret sauce" is delivered to McDonald's restaurants in sealed canisters and is dispensed using a special sauce gun - similar to a caulk gun - that releases a specified amount of the sauce for each pull of the trigger.
