It was founded by "three friends" after an "inspirational trip." The authors explain the purpose:
"This is purely for entertainment purposes and strictly limited to the outrageously bad / ugly / creepy / crazy shoppers. We don’t need to see pictures of you and your dumb friends dicking around at Walmart. There is no reason to send us pictures of people that are seriously and unfortunately handicapped so don’t be an asshole. We are trying to have some fun here and there is a difference between someone who is mentally challenged and a person who has a fu Manchu and is still rocking MC Hammer pants."
PS: Why is there a Busted Tees advert in every single viral comedy site? Every single one.
