I don't know it you all have heard, but there's a FNAF musical by random encounters on YouTube and both Markiplier and Natwantstobattle star as the security officer. I was going to put this too for if you're having a bad day.

Here's the first night, look up the rest on YouTube, but Markimoo's singing voice though.

Ere are the bloopers for night 4 that I found hilarious, watch it. Mark fucking dabs, whips, and nae naes at the end I'm done XD
