The mighty "Ghost Pepper" can humble even those with the highest tolerance.

Got a friend who's always boasting about his tolerance for spicy food? Now's your chance to put him to the test (and maybe watch him cry).

The Lion Head Pub and Finn McCool's are both hosting "Hottest Pepper in the World" eating contests Thursday night; brave contestants will make their way through a variety of peppers, from the mild bell variety up to ancho, cayenne and habanero peppers. At the end comes the big boy, the Naga Jolokia (aka "Ghost Pepper"), which has a heat index close to 1,000,000 (a bell pepper is 100-500, for comparison). The whole thing keeps going 'til there's one person left, and that person wins a 32-inch plasma TV.

The fun starts at 9 p.m. at both locations, and contestants must be 21 or older. No word on whether they will play Mims in the background.
