The QUICKEST way to do this is at the boss of the very first level. Just stand there without ever attacking him (Scary bunny with the crown on one ear) and stick your hands out directly in front of you everytime he throws a ball at you (he will glow blue right before releasing it). Sometimes my kinect sensor won't recognize the catch for whatever reason. No worries though as it does not matter if you die and restart the level as there is another achievement for retrying a level 10 times.
This achievement should only take you 10-15 minutes if you are starting from scratch. If you do end up beating the level, just exit the game at the next screen and pick that level from the main menu and play it again.
