Go for it! I have gotten jobs that way hehe.
Some managers like a relaxed person with a sense of humor. Then others tend to put things like "Talon is not serious enough" in reviews so... it is a toss up. I have told my manager that Global Domination is one of my long term goals.
*sigh* I've had a number of interviews here where no one has had even the slightest sense of humor. Come home feeling like a total loser.
This time, I don't care. Just doing it to do it, and I dunno why.
