Extract from J's work journal: A fish pond in an office (pic) that overflew and caused a million dollar worth of damage. Somebody, possibly, forgot to close the faucet before leaving on Friday afternoon. I asked the owner if the fish had died. Typical J galgenhumor. The pompous answer: "I shall answer you in court".
Another example of galgenhumor (from the wiki): The rate of Jewish intermarriage is a serious problem. Scientists estimate that unless something can be done to stop intermarriage, in 100 years, the Jewish people will be reduced to a race of gorgeous blondes.
