The Bubble Gum

Problem: Schnickelfritz has two friends over and only one piece of bubble gum to share.  The fraction was the easy part, these boys knew the gum needed to be divided into thirds.  My problem as the one with the knife was ensuring the pieces were as equal as possible. Being an only child and having an only child I had  not been party to the intense analasys that occurs to see which piece was actually the biggest.  I almost offered to get out a micrometer.   The outcome--the boys chewed the gum for far less time than they inspected it.
