#6 - Rasputin
#5 - Severus Snape
For starters, she has an awful dog. She's cruel and would probably talk smack about your family the whole time. Not to mention she would drink all your liquor.
He'd be the worst, hence his name. He looks way scary and he prances around in a cloak and top hat trying to lock children in cages. You would shut yourself in your room trying to be silent, but he would be right on the other side of the door saying, "Lollypops.. Icecream.." and when you started propping large objects against your door, he would go around outside and peek in your window.
Granted, he wouldn't be the most fun. But you would feel really protected while he was there. If a bully threatened your safety or if anyone tried to wrong you, he would beat their sorry behind and then drive you across the country to somewhere even safer. Really, would you complain if someone who looked like that showed up at your house?
She would sew you a new outfit, take you on a sweet day trip through the city, and play the guitar and sing for you. Then you could make happy lists.
#1 - Mary Poppins
She's obvioulsy the ideal babysitter. You wouldn't have to worry about cleaning up your toys. She and Bert would probably take you on a cool adventure, she would let you sit on the roof enjoy the city at night, and sing you to sleep. Oh, and she can fly and has magical powers.
Babysitters are kind of like sushi; they're either really good or really bad.
