Oxygen Etiquette

So at some point on Earth Day, A. learned that each tree creates enough oxygen for 8 people. He went outside for a while, then informed us that we can't have more than 48 people in our house at once.

Because we only have 6 trees and it would be rude to invite people over and then not have enough oxygen for them.

I think I'm raising Dwight Schrute.
