Empty backlog board hits different than a clean kitchen counter.

The face touch thing is real but the timing is usually backwards from what people think. In a lot of those clips it's not a signal before the voice crack, it's a self soothing move that comes after they feel the crack coming, so the hand starts moving about a second before you hear it and people just edit it to look like a tell. Watch any awards speech on .5 speed and you'll see the hand go up while the mouth is still steady.

I did that with bacon grease once and the blade smelled like breakfast for a week.
