Sense of humour?

I was reading The DaVinci Code and i read something funny.










The one above is a well-known male symbol, however, the male symbol wasn't like that in the old times. The one below it is the old male symbol. It represented a rudimentary phallus, which means penis. It was modified, however, it is still used today on modern military uniforms to denote rank.


Quoted from The DaVinci Code:

"The more penises you have, the higher your rank."

I find humour in that sentence.
