Here's the right idea

G. S. Springer, a geology professor at Ohio University,  has a cartoon that emphasizes the fact that the normal curve describes the distribution of measurements on a number line. Small measurements are on the left and large measurements are on the right. Those in the middle at "the top of the bell curve" are just average. These two getting ready to sled are "at the top" because they are average and there are so many others that are also average. The real "top" of the normal distribution are those large measurements (and sleds) on the extreme right of the number line.
