Also, the field generated by a
Secretaria de Educacion Publica (the
Mexican Ministry of Public Education) bureaucrat.
It is known to cause neural disruption in otherwise normal people. Probably associated with a bogon field, but with
further unexplained effects, like forcing high school students in strange rectangular patterns, or making otherwise reasonable people start to sing the national anthem.
The only way of protecting yourself from the SEP field is to stay well away from SEP, or wearing disreputable clothing. This will make the bureucrat perceive you as a completely useless person, and turn the withering blast of his field towards somebody else.
Another technique, an advanced one, is to square off the SEP man against a bogon sink, like an UNAM university professor. The result may well be a normal environment.
