What is the difference between Karate and Tae Kwan Do?

[Vicious]

Didn't you guys watch Karate Kid. That's probably where JJ learned that from. Because somewhere in that movie, Mr. Miyagi mentions that Karate is from Okinawa and that's where he was supposed to be from.

Anyways, I took Tae Kwon Do, and it really is a waste of time if you want to learn how to fight. I took it as a kid, but you'll never use any of that stuff in a street fight. And they do waste alot of time teaching your forms and stuff.
