Schoolboy Error 

Schoolboy Error: (n.), (der. old English), A mistake, often trivial, clumsy, dimwitted or easily avoided. Generally shameful in hindsight, but without cause for embarassment, owing more to circumstances or instantaneous bad luck, rather than serious incompetence of behalf of the maker. Derived from the "trial and error" psychology present in Victorian-era English public schools.

Upon dropping the soap in the Violent Offenders' Wing of Barwon Prison, Eric cursed his schoolboy error.

Dr. Feynmann lowered his glasses as the fruit of twenty minutes labour yielded an unwanted result: E = mc^2/0. "Well fuck me", he said, turning to the class. "I seem to have made a schoolboy error."

schoolboy error 

The most basic of errors. An error so simple, and avoidable, that anyone with an ounce of credibility or experience in that field should not be commiting it. A mistake that should only be made by school boys still in training for that particular task. Especially used when referring to playing games of pool in pubs, or occasionally during snooker. Schoolboy error can be heard ringing out by jeering onlookers if for instance a participant missed a sitter = he should have potted it as it as so simple, that thereforehe is reduced to the level of a lowly school boy playing his dad for the first time.

And here comes Keane for the winner....Oooooooh and he's missed, and left the black right over the pocket for Swann to tap in...
Schoolboy error!
