Q. What do get if you multiply 6x6x6?
A. 666! This is a very dangerous number, as it reads the same backwards as forwards - what mathematicians call an "aerodrome" - and if turned upside-down can summon the police. DO NOT SUMMON THE POLICE WITHOUT A RESPONSIBLE ADULT PRESENT THEY CAN TAKE AWAY.
Pah!
Laughs. Loud.
