Run free, little Bob!

HELP!
Does anybody know what movie "Run free, little Bob!" is from? I've been searching everywhere, and it seems like it's used widely, but I can't find the source for this quote. If anybody knows, please help.
Thank you
Cherry

It's from Harry and the Hendersons, The dog's name was "Little Bob."

Good call sharpy...
