Vesper

“There is always Joker to see through the delusion. Generation succeeds generation, but there is a fool walking the earth who is never ravaged by time.”
― Jostein Gaarder, The Solitaire Mystery

“When a joker dies, the joke remains.”
― Mokokoma Mokhonoana, The Confessions of a Misfit

“[He]... watches the Joker rising from his wheelchair, the way a rabbit watches car headlights bearing down, unable to move a single, spotlit muscle. The madman's limbs appear to unlatch as though some psychotic god has chosen to give life to a complicated Swiss Army knife. The Joker's head rotates... the green lasers of his eyes target the keys at the big man's belt, and he shakes his head.”
― Grant Morrison, Batman and Son vs. the Black Glove
