guess my word not working

I know I have things wrong.  It runs, but not how I want it to,
first error:
the first random word it picks is 'said'  every time.  That's not random.
second error:
It doesn't restart the game cleanly.  Things print I don't want it to.
third error:
It doesn't pick a new random word until the third play through. First two words are said.
fourth error:
It doesn't close properly when you tell it that you do not want to repeat.

I'll post a corrected version when I figure it out.  Once again the cheat it the back is almost completely useless.  Learning the hard way.  Hurray.
