2 + 2 = ?

If someone researched the issue I’m sure they would find a spike in child abuse cases week nights between 6:00-8:00 p.m.  The exact same time when tired, overworked parents nationwide are sitting down and attempting to do math homework with their stubborn 6-year-olds.  And the kid is rolling on the floor arguing that 2 + 2 doesn’t = 4.  It equals 3, 5, 6, or 7, but never, ever, ever, under any circumstances, does 2 + 2 = 4.  Never.
