I'm really not sure why people eat insanely spicy things.  There are definitely people out there that just like the taste, but I have to believe that the majority of people who do this, do it for bragging rights.

When I was in college, I was told that I wouldn't be able to eat even five suicidal chicken wings from the local pizza shop there because they were so incredibly hot.  My response was, "I'm from Buffalo!  I can eat any chicken wing you put in front of me."  Then I upped the bet.  I told them that not only could I eat five, but my roommate and I could eat an entire double order.

This was the worst I idea I ever had.

In short, we were able to eat all 20 wings (I hate to lose).  But it was immediately regrettable, and that regret continued right straight through the next couple days.  Needless to say, I am not a fan of hot/spicy food at all.  I'll pass.

But check out these two as they eat what they call "the hottest pepper in the world."
