»A standard comedy piece: something absolutely insane is going on, but only one person notices. That person attempts to show everyone else that the occurrence is insane.

There are usually three stages: Bewilderment, Trying to Explain, and Violent Sarcasm. In the first, the OSM looks around and realizes that something is wrong. In the second, he tries to explain why it is wrong to those who are accepting it as normal. In the third, he start to yell, groan, cry, howl and berate, in a hope that someone will notice.

Sadly, nobody does.«
