5. Baldrick Blackadder
"If you want something done right, kill Baldrick before you start." That sentence alone should be evidence enough not to open your home to Edmund Blackadder's dim-witted sidekick. He may be doggedly loyal and easy to manipulate but his utter stupidity and appalling personal hygiene (this is a man who regularly eats dung and rats) easily outweighs that. Leave a priceless manuscript lying around while Baldrick's about and it'll end up on the fire. Give him an obscene amount of money to bribe the House Of Lords and he'll spend it on a turnip. And only once in a blue moon is one of his trademark cunning plans anywhere near cunning. And finally, if he offers you a cup of coffee, whatever you do, don't drink it. Unless you happen to be fan of hot mud mixed with saliva, dandruff, and some very dubious chocolate sprinkles.
