Best Grinch Impression - JIM CARREY - LIVE Looping voice over

How do I do this?
Simple. I watch the original clip about a million times, memorizing the timing, then I record at the same time, HQ audio into a Yeti mic, while filming the performance on a phone. When it's all done, I sync up the audio and video.
Hope you enjoy!
