It's silly to find it amusing I suppose but I just spotted this book on Amazon UK:
http://www.amazon.co.uk/Improve-chess-shortcuts-tesujis-tendons/dp/7500945655/ref=sr_1_7?ie=UTF8&qid=1409837953&sr=8-7&keywords=tesuji
"Basic tesujis coping with vulgar tendons"
"The first chapter introduces a tesujis. Eat son tesujis"
&
"Nothing caused by the other son tesujis"
- sounds like something I might need as my son has just started school..It looks like an interesting book btw, guessing by what the translation is probably supposed to be and I've never seen it before but its too expensive for me at that price (93 GBP).
