Near the end of the episode, Kirk is trying to persuade the irrational children to help him save the planet, and the children just keep yelling "Blah Blah Blah!"

Kirk says:

No "blah blah blah"! Because... if you don't help us, there won't be any games anymore. There won't be anything. Nothing... Forever and ever...

...I'm begging you: let me help you! Or there won't be anything left at all.
