Is 検便 happiness?

*Italics are spoken in Japanese*

Teacher 1: Annica-sensei, please teach Teacher 2 how to say "kenben" in English. 
Me: Kenben? I don't really know... what is kenben?
(I pull up my internet dictionary and type in "kenben". Some kanji comes up.)
Teacher 1: Yes, yes, that's it! In English?
Me: Uhh... "feces examinations".
Teacher 2: Ahh... THANK YOU VERY MUCH.... Feces... Examinations? In Japanese, "unko kensa".
Me: Oh... thank you...

(Thirty seconds later)

Teacher 2 (to another teacher): Hmmm... What is happiness? In English...?
Me: Uh, "happiness".
Teacher 2 (to me): Please... teach me about happiness!
Me: ..... I don't really know...
Teacher 2: Shall I teach?
Teacher 1: NO.
