It's nearly here - the first 'The Simpsons' and 'Family Guy' crossover episode.

A five-minute clip was previewed at the San Diego Comic-Con this weekend and it looks amazing.

The Griffins arrive in Springfield and are initially given a warm welcome by the Simpsons, despite both being suspicious of each other's colouring.

Peter warns his family: "Don’t drink the water around here… everyone around here looks like they have hepatitis."

Inevitably things turn a little with an argument over beer turning into a full-blown nuclear-powered brawl.

It's bound to be a classic

The one-hour special will be aired in September.
