In my home town there's a particular Indian curry house that's sports the "curry challenge."
The challenge is to eat the house's hottest dish (which is some fucked up concoction called a 'faal') without any water. If you can do it you can eat and drink as much as you like and your entire bill is on the house.
In the unlikely event that you do manage to eat it they stand you on the table, everyone claps their hands and they give you an oversized medal.
I've only ever seen a couple of people complete it but there was a couple of students that would come in and eat it regularly. These guys could be seen suffering, crying into their meal and sitting with their mouths open trying to relieve the pain. The curry was so hot that the chilli would burn red lines into their skin where their noses and eyes ran.
Students
anything for a free meal.
