“People like eccentrics and they will therefore leave me alone, saying that I am a "mad clown."”
As quoted in Vaslav Nijinsky : A Leap into Madness by Peter F. Ostwald, Ch. 8: Playing the Role of a Madman, p. 176
Unsourced variant: I know everyone will say "Nijinsky has gone mad," but I don’t care because I have already played the mad man at home. That is what everyone will think, but they won’t put me in an insane asylum because I dance very well and give money to anyone who asks. People like eccentrics, so they will leave me alone and say I’m a mad clown. I like the mentally ill because I know how to talk to them. When my brother was in an insane asylum, I loved him and he could feel me. His friends liked me. I was eighteen then. I understood the life of a mentally ill person.
