Here are some people who deliberately existed somewhere and under certain controlled conditions. It has been documented, so please examine the evidence. Wait a second. Who are you? I'll have you know this is a restricted area. Only those involved with the evidence may enter this section of the premises. You are unwanted here, although, perhaps you may want to stay and examine the evidence with me, since you look like a perplexed and reasonable individual with an efficient pointer finger.
Well, what do you think? Do you not agree that those people are existing quite deliberately? It seems self-evident, but we are just double-checking. Direct your attention to the room in which those people are existing. You cannot disagree that rooms are somewhere, so, by default, anything within the room is also somewhere. It just makes sense. Those people are, without a doubt, in the room, and furthermore, they have decorated it with their intentions, which you can observe scattered about the room.
It doesn't matter what their faces look like, nor does it matter how much time they spent preparing for the documentation of their existence in that room. What matters is that we are now observing the evidence, applying fair judgment, and appending the whole analysis to our collective consciousness, in order that we might accurately dislike these people.
Now, let us go have sexual adventures with numerous transvestites simultaneously.
