Some merchants at farmer’s market make you sign a waiver before they will sell you the super-hots...
That’s funny. When I handed a bag of the XXXhots to a friend, the one who can eat any chile, as a joke I made the disclaimer “I take no responsibility for any injury you may incur.” Sure enough a few minutes later I hear him cry out “@Q%$#%#!” He handled a chile and then forgot and rubbed his eye.
