OMG, you just made my day! I watched Internet Shaquille years ago and really enjoyed him but never subscribed. Then I forgot his name and have tried many times to find him again using the few things I remembered from his videos. Never found him though. And now, you posted that little name and I instantly recognized it, thank you so much :D
