At Heathrow Airport today, an individual, later discovered to be a public school teacher, was arrested trying to board a flight while in possession of a compass, a protractor, and a graphical calculator. Authorities believe he is a member of the notorious Al-Gebra movement.

He is being charged with carrying weapons of math instruction.

Jaja...Al-Gebra kenne ich, von Al-Gebra wurde ich schon in der Schule terrorisiert :-)))
