Well, I outran SCP-173 a few times, and that thing is persistent; and hearing it open doors behind me made me feel like I was in Jurassic Park outrunning Velociraptors (had to spend a few seconds closing the door everytime it opened them up until it gave up for the moment, or it was possibly outside my visibility range when it enters the room (damn thing's smart). Fortunately, I managed to stop it by locking myself in a keycard-required room. Unfortunately, SCP-106 was waiting at the bottom of that well, and I couldn't find my way out. I never felt so helpless.
I wasn't as much crying in fear when I saw it, than basically screaming "SCREW YOU!!!" at the screen as I was trying to outrun it around the boxes. If not for the gasmask I was wearing, I probably would have noticed the edges of the boxes better, and not get slowed down by the corners. Doesn't help that that old man is rather spry and quick.
EDIT:
And in hindsight, rereading his article, can pass through solid friggin' matter. FFFFFFFFFFFFFFFUUUUUUUUU---
EDIT EDIT:
Just learned from the Foundation itself that Bobble the Clown is
running away from his taxes has escaped. I would hate to stumble across him while evading SCP-173. I mean, keeping an eye on that thing through the video screen, and then all of a sudden, Bobble's show airs on the screen in a few moments distracting you, and possibly knocking you out in the process, as you hear the others close in on you? Aw crap.
I would believe keeping your eyes closed or averted from the screen the very second you notice it ought to give you enough time to evade getting affected by it. Of course, as you look away,
it mocks you for not taking an interest in watching quality programming. Unlike 173, not looking at, or blinking rapidly is actually a good thing if it makes it's appearance. It may or may not also make the game that much creepier as you hear a cheerful kid's show broadcasting through this hellhole of a maze. Be cautious, however, if it decides to work in conjunction with SCP-173. You may not be so lucky everytime if you survive waking up after the show. Then again, something like 682 just wanted to wait for you to wake up before tearing you apart.
