We think it's safe to assume this duo are glad they don't walk a little bit faster -- because if they did, they'd be toast.
That's because as they were walking along a pavement in Peterborough city centre a manhole exploded and a fireball erupted in front of they.
Video footage recorded by CCTV camera outside a nightclub shows the duo jump in horror as the flames flash up from where they were about to walk.
While BT engineers are looking into the explosion, some people claim it must be a gas leak… though we like to think it was the Peterborough dragon.
