You’d think the reasons for something being funny were beyond the reach of science – but Google’s brain-box researchers have managed to come up with a formula for working out which YouTube video clips are the funniest.
Their algorithm has declared that a video of a cat appearing to say ‘no’ over and over again – called No No No No Cat - is currently the funniest.
The video only has just over 60,000 hits – which is small compared to the millions some clips clock up – but Google turned its attention to the comments users leave to gauge comedy value.
