What's the dumb thought rattling about in your head at this moment?

Shredder is a moron. Massive space-age fortress, near infinite vehicles and robo-ninjas, obviously lifts, and yet... he sends a nuclear submarine to kill the turtles, which are in miami, so he can steal manhattan. I mean, come on bro, if you kept that submarine, you could have stolen the city and been done with whatever.
