One of these days someone will breed a pepper that will spontaneously combust when ripe. Then the SHU will have to be changed to the ETU (ExaThermic Units)...and no need to light the weed burner any more.

Personally I dislike my face being melted and habanero's are at my limit with a quart of milk standing by. Had a Thai friend once make me his version of Soba which took a day before I could taste again and him to stop laughing...still can't eat those little red/green bastiches to this day.

Guess we'll have to wait and see if the Pepper X is the next face smelter.
