Wow! I can't believe I've been doing this almost 10 years now and I haven't posted the theme to Alfred Hitchcock Presents. Its a great theme, one I first heard as a kid on Nick at Night.
I was only 4-5 so most of that show went over my head but I could tell it was scary. The stories were always more of a thriller type then something gruesome like Tales of the Crypt but that didn't make them any less haunting. In fact as I've gotten older the things that are more within the realm of reality are what scares me more than monsters and demons. No disrespect to Monsters and Demons.
