If we can bring back knowledge capable of changing it ... The future.

I'd love to know WTF some of my ancestors could possibly have been drinking.

(I meant to say "thinking," but that's probably why they did most of what they did.)

Chewing with mouth open

Popping gum

Blowing nose at table

Thinking that you have the right to do whatever you want, regardless of the effect that it may have on others.
