Watch: Yoko Ono cover Katy Perry

It seems as if Yoko Ono got really bored at an art exhibition, and with little urging, got up and gave the crowd an impromptu one woman karaoke session. A writer over at Jezebel called it her 'favourite thing in the entire world' but after watching, or perhaps more pertinently, listening, to Yoko Ono belt out Katy Perry's Firework, we're not sure you'll be able to agree. Or, rather, you might agree, if the sound of a neighbourhood cat with special needs caught in a steel trap while someone dangles tuna over its head coincidentally happens to be your favourite thing in the entire world too.
