On CFOX radio in Vancouver*, they do this thing called Hump at the Pump. Basically, they find two complete strangers and get them to make out at a gas station, pumping gas into their cars for as long as they keep making out. The radio guy pumping the gas gives a play-by-play over the radio and then they put the video of it up on the net (click here to witness an example of the debauchery).
So, the question is: would you make out with a complete stranger for free gas? Keep in mind that here in Vancouver, gas currently cost about $1.20 a litre. (For my American readers, 1 litre = 0.264 gallons... so we are talking like $4.50 per gallon).
*I'm willing to bet that they do this at radio stations in other cities too. Radio stations seem to be the same no matter where you go.
