A man was bored and always bothered with existentialist pain. He was a nihilist and he was proud to find no meaning in life. He was proud to stand in front of life and say, "you're stupid". But one day, he got very depressed over something, and he tried to suicide. He did not die though, so he felt even more miserable.
Then as doctors gave prescription to, he started taking antidepressants and lived happily ever after.
