This is MEMRI's clip number 6666, which seems appropriate for someone who is saying Jews are Satan.

Here's the funny part: The story is true, except for the Jewish part.
From Wikipedia:
The first ever Roman fire brigade of which we have any substantial history was created by Marcus Licinius Crassus. Marcus Licinius Crassus was born into a wealthy Roman family around the year 115 BC, and acquired an enormous fortune through (in the words of Plutarch) "fire and rapine." One of his most lucrative schemes took advantage of the fact that Rome had no fire department. Crassus filled this void by creating his own brigade—500 men strong—which rushed to burning buildings at the first cry of alarm. Upon arriving at the scene, however, the fire fighters did nothing while their employer bargained over the price of their services with the distressed property owner. If Crassus could not negotiate a satisfactory price, his men simply let the structure burn to the ground, after which he offered to purchase it for a fraction of its value.
