Unnoticed Obvious #0001

Every now and then something crops up in converstaion that makes me realise something that should've been blatently obvious. Welcome to the first in this irregular series.

Today someone was referred to using a term from "Monty Python and the Holy Grail". The term was "Kerr-nig-itt" (a phrase uttered by the tauning French sentry man, whilst hurling insults at King Arthur and his Knights).... I then realised that this man's surname (being Knight) was the realise a colleague used this term of endearment.

"So "kerr-nig-itt" and Knight are the same thing ?", I asked
"Errrrr..... yes", my colleague repsonded

Estimating that I first saw the Holy Grail around 1980, this joke has taken 26 years for me to get.
