In the index of this book, under j, he references several 'jokes' found throughout the text. I can't find one on page 91 - anyone know what it is?

Dear Robert, the joke on page 91 is that the ruled quadric depicted has "Central Electricity" written over it. It is an allusion to the cooling towers used by power plants. Here is the obligatory Wikipedia link:
