When something funny is equally sad.
When you realize you are working full-time and going to school full-time, with absolutely no expectation or hope of retaining your sanity.
When a friend laughs at you for being excited to take a day off of work in order to study all day for an exam.
When the magnitude of how pathetic your life is becomes entertaining.
That is the essence of two legged cat.
I am become meme.
