Little bit of dry humour from the science joke website continuing the whale theme from Friday/Saturday’s events on the Thames:

“The species of whale known as the black right whale has four kilos of brains and 1,000 kilos of testicles. If it thinks at all, we know what it is thinking about.”
Jon Lien, “Whale Professor” at St. John’s University, Newfoundland, speaking to the Norwegian Telegram Agency (spring 1995).

Or if you prefer exams:

“From an ecology exam at the University of Nottingham:
Q: What is the consequence of the extinction of whales?
A: “The sea level will fall, combating the effect of global warming.”
