So many TVs...
There had to be at least 200-300 old CRT TVs set up and scattered around the asylum. Where the hell did Jigsaw and crew get a hold of them all? They must have raided an abandoned TV factory. And how did they transport them all to the asylum? Must have taken a few trips. You'd think someone would have been a bit suspicious about it.
Yes, I know questioning the realism of this game is futile, but it's pretty funny when you think about it. It took long enough to get through the asylum's traps and rooms - imagine how long it would have taken to set it all up? And what would have happened if one door malfunctioned? The whole plan would have fizzled... Anyway, yeah. ;)
