      this is a surface integral so the joke is (loosely): as opposed to peeling in straight strips (line integral), grandma is peeling continuously without lifting her hand

      It’s a surface integral of a vector F over a surface S. I guess they are extending the joke from 1D to a 2D surface which is smoothly integrated (peeled).
