Scariest Crap In You Pants Moments

[Disruption]

My worst moment was...this is a little scare not many people run into, go into the Archives, cause the little cave in, go back into the hall with the two fireplaces at either end after the cave in, go where to rubble has sealed off the corridor, turn and look at the corridor, enjoy pissing your pants

I hate my friend for telling me about it, he was like "go do this" and I was retarded enough to not be suspicious, but needless to say, this particular scare me hit 'exit'

I won't tell you what the scare is if you haven't encountered it

I just got to the archives. Mind telling me what it is in a spoiler?

EDIT: Nevermind, I saw it on YouTube, haha. I won't be doing that.
