Hmmm... I mean, I don't really have any hope of beating any of these guys. I mean, Laurie Strode has somehow been able to survive Michael Myers's onslaughts over and over again, so if she can do it, I could do it, right? Maybe?
Frankenstein's monster is slow, and even sometimes portrayed as friendly, so I'll take my chances there.
That leaves Dracula and the Wolfman. Dracula can really only come out at night, but he's undead, and silver bullets are hard to by. And I doubt I'd ever be able to get close enough to use a wooden stake. As for the Wolfman, I don't know enough about him to assess his weaknesses, but I have to imagine that he's fast, probably much faster than me. And he probably has some kind of super strength.
Alright, I'm going with D as well. I don't want to meet any of these guys, but death is almost a certainty no matter the choice, and who knows how long or torturous Mike Myers would make it.
