This thread intriguied me for several reasons...
1st, I find my friends and I throwing the saying "I KNOW RIGHT!?" arround often. We use it to express shock and wonderment. So we have taken to abreviating it as IKR for txt'ing.
2nd, International Karate for the Commodre 64/Apple/II/Atari ST was times abreviated IK or IK+, but I dont know where the "R" in this video comes from.
3rd, The Characters in the Video, and the Music is inspired by Ye Are Kung Fu. Another great C64/AppleII/ST game. right down tot he fat guy falling on the ground and tiwching his foot on defeat... but the guy with the Bo staff was not untill the 4th Attacker named 'Pole' IKR!?

Lastly, That First scene that the character in that video is running through is right out of 'Kung Fu Master' by Data East.
