The cinnamon challenge is basically swallowing a tablespoonful of cinnamon with out the aid of water, which sounds pretty easy until you try it. These two chicks are all set to down some cinni, but one ends up with a mouth of cayenne pepper instead.

 

First of all, the audio is kinda jacked on this video, so take that into consideration when you press play.  I guess this couple Nikki and John do prank videos on each other all the time and this has to be one of the funniest.  When Nikki is screaming and her friend is just laughing and puffing out cinnamon had me rolling.
