Humphrey would be adorable on an animal (like the
Humphrey the Whale mentioned already. I just think that's so cute) but not so great on a person. Then again, I do get a tenacious vibe from it, so maybe the right person -could- pull it off.
I -hate-
Nikita on a girl. I think it's just a bit tacky.
On a boy... hmmm... I can see the appeal. However, it's one of many Russian names which probably won't fly outside of Russia, sadly. And as much as I like the sound,
Nikita Krushchev pretty much kills it stone dead for me. He was not a nice chappy.
I still like
Nikita better than
Niketas, though.
