Teenage Mutant Ninja Turtles finally Learn how to use Their Weapons

I loved watching the animated Teenage Mutant Ninja Turtles TV series when I was a kid. As you know, all those times that they fought Shredder and his goons, not once did they ever draw blood with their weapons. Thanks to College Humor, the turtles have finally discovered how to REALLY use their weapons properly in battle. Yes, the blood will flow in the sewers.
