So easy a child could do it. The phrase is used to describe everything from assembling toys to programming remote controls.
And now, for sneaking across the border from Mexico into the United States.
Border Patrol agents in Arizona and Texas have been overwhelmed by thousands of "UAC" illegal immigrants. The abbreviation stands for unaccompanied children. So many have come across the border during recent months that the agency has put out an emergency call for babysitters.
Many of them are from Central American countries. Somehow, perhaps with adult help, they made their way across Mexico to where they could enter the United States illegally. Reportedly, some of their parents believe that once the children are here, they will not be kicked out.
"It's a humanitarian disaster," Sen. John Cornyn, R-Texas, said recently.
It is that, and President Barack Obama's administration seems to have no good plan for dealing with it.
But the influx of youngsters is something else - proof claims by the White House that our southern border is secure are false. When children unaccompanied by adults can cross the border illegally, "secure" is not a word most people would use.
