The Tower of Terror is, well, terrifying, but once I get off I laugh at myself for being scared. The same with the Looping Starship, though I wasn't that scared while on it, just for a few minutes afterwards. There's a lot of rides that scare me before I get on, but when it's done I usually think they're mildly amusing or fun. There's never a thrill ride I've been on I haven't liked. I'm a little scared of going on Behemoth, but I'm sure once I'm over the first drop I'll enjoy it.
The one ride that I am really terrified of are those giant slides. I'm nervous going down regular playground slides, so I will not even go near a giant slide. My sister tried to get me on one a couple days ago. I ended up turning back around halfway up.
