Como medir la estupidez/How stupidity is measured

Ser un buen tertuliano, no capacita para ser un buen ministro de Educación...

Translation of the graffiti:
"Work is measured in Joules
Force is measured in Newtons
Frequency is measured in Hertzs
Stupidity is measured in Werts*"
*The current Spanish minister of Education is José Ignacio Wert
