Japanese name 錦戸

Hi everyone,

what does the Japanese surname 錦戸(Nishikido) mean?

Also, I am looking for some kind of pun, play on words or other joke using the name 錦戸 – either the sound or the meaning. It doesn't have to be a *good* joke, but unfortunately, I don't speak Japanese and so can't come up with anything at all. :-)

(As an example: A guy called 田口 uses the pun "入口, 出口, 田口 です!". I'm looking for something along the same basic lines for 錦戸. I'd be very grateful for suggestions!)

Thank you for your help!
