There were a few kids in our school unfortunate to be born with Down's Syndrome. One of these was particulally violent when provoked by somewhat unusual things. For example, fire alarms and pencils. When on one of his funny turns, he was granted tremendous Mong Power by the Lord, and would deal out tremendous, often uncalled for beatings to anyone who got too close. We didn't see much of Mong the Merciless after this had happened a few times, as he was forced to leave our school to be moved to a special unit. God knows where he is now, but I wouldn't be suprised if it was fairly secure and had plenty of sedatives near by. Poor Bastard.

Mong Power is this special ability you speak of. I have witnessed it many times. It is not entirely native to people with Downs, it is a genetic condition that appears also in Gingers, some closet Homosexuals and people with other abnormalities. Some examples of these are as follows: Goofy teeth and/or braces, freckles, acne and/or other hygiene deficiencies, spectacles, close resemblances to family members, wearing pants that are too short.
Mong Power is a force of nature and once unleashed it cannot be easily stopped. It is the only evidence of supernatural powers. A single Mong, once enraged, is capable of lifting more than 50x there own IQ in kilograms, which is in fact, quite a lot. Not only do they have incredible strength, but for the period of their rage, they are impervious to pain. The only way to remove them from the enraged state is a finger in the anus or to lob off the head. Unfortunately, fingering a Mong's anus is illegal in the UK without permission from the anus's owners guardian and beheading is also illegal unless your are in Birmingham or another area operating under Sharia law.
