I LOVE a nice, juicy, tart Granny Smith apple; however, I have NEVER consumed one in my life that didn't have me outgassing like a champ before I took the last bite...I suppose it's something unique about my biochemical makeup, but it's so consistent you could set your clock by it.
I will indulge prior to my next flight. The TSA wants to search granny? I'll deliver her to them.
Yeah ... who doesn't?
