I'm about to brag. Consider that your warning.
My now 12 year old has always been amazing at guessing the number of [X]'s in a [Y]. He has, at least 3 times in his life, won guessing games at fairs or carnivals that depended on that particular skill.
Today at his schools scheduled goof-off day, he won again, by being the closest.
There were 774 skittles in this jar. His guess was 771.
There are less in there now. A guy's gotta make friends.
