For ****s and giggles i've tried the Bhut Jolokia and the Moruga Scorpion peppers. Both make your face bleed and are painful the next day. I still want to find the Carolina Reaper which is apparently the hottest pepper currently on the planet. I avoid straight Capsicum because I don't like ass bleeds.
