I am trying to find a simile or metaphor that best describes the uselessness of the education lottery. The winner will receive a prize.

Early entries include:

As useless as the Currituck ferry

As useless as a DNA test for the 47th member of the Duke lacrosse team

Useless as an Ann Coulter doll to John Hood

Useless as a Dukakis campaign poster

Useless as the definite article to Tonto

Useless as an ashtray on a crotch rocket (don’t ask)

Useless as sound science to an environmentalist
