In the popular programme Dallas, the Ewing family own a petrol business. To launch the Season 3 première, for one day only, TNT had the Ewing family open up their flagship petrol station in New York. They were selling petrol at $1.98 a gallon, and this caused chaos for up to 8 blocks in every direction.
A fantastic stunt, with fantastic results. All the surrounding petrol stations were deserted, and some people were queueing for 4 hours!
