We were about fourth in a long queue waiting to take off in our larger Boeing aircraft. The JFK ATC allowed a B737 on a local flight to take a short-cut and start his takeoff run by joining the main runway from a taxiway causing us to wait for him to take off and clear.

Half-way along the B737's takeoff run, 'someone' held their cockpit mike to the horn and pressed it as they tested it. The B737 abruptly stopped takeoff with full reverse and full braking and shuddered to a halt, tires (tyres) smoking. A few seconds later we heard a voice on our VHF: "How do you like them apples?.."
