If you could imagine the worst possible zoo that you could ever find yourself in, what would it be? David Brown's Zoo from Hell would feature 3 exhibits: 1. Brown rat nocturnal walk-through exhibit. My memory of the brown rat exhibit in the London Zoo nocturnal house still gives me the creeps. 2. Small, yappy dog immersion exhibit where the dogs yap and growl at you as soon as you get within 50 feet of the exhibit. Isn't it fun when you walk by someone's yard or car and their miniature dog barks and growls at you? Imagine the joy of that replicated in a zoo! 3. Pigeon walk-through aviary. Come get pooped on by flying rats!
