Since when did GLaD stalk you? Last I checked, she was mounted from the ceiling. Anyways, when I was very little and playing Super Mario 64, the thwomps always scared me to death. I have absolutely no idea why, they just did. Also, when I first came across them, the detons startled me greatly. But, the one that beat all for me were the wallmasters from the Legend of Zelda.ola said:GLADOS from Portal
