The Simpsons creator Matt Groening has picked a suitable epitaph for his gravestone – his cult cartoon character Homer’s catchphrase “D’oh!” Groening has accepted that the saying, which has become a world-wide catchphrase following its repeated use on the massively popular TV series, will follow him after his death – whether he likes it or not. He jokes, “Even if I don’t put it on my grave, some fan will spray it on.”
