I'm willing to entertain the possibility that the light we're seeing near the opening to the tunnel just might be the tour guide.
Now that I think about it, that guy does look a little familiar. But the last time I saw him I remember he was holding a clipboard and a microphone rather than a flashlight. Perhaps they break the flashlights out when half of the candidates keep reappearing in Hall A? He's probably coming to show us the way out.
Sshhh ... listen ... he's close enough now ... I can hear him calling to us ...
"Walk this way, folks. Just a little further. There's a handful of passing scores in the jar on your right. Didn't you see them when you were leaving last time? Ah... more's the pity. It would have saved you so much time. You were probably making snide comments about those 'Rules 12 Violations' when we were giving the 'Passing Scores' instructions. Well, no bother. Please help yourself and we'll be out of this black-pit-tunnel-of-despair thing in no time. Come on, folks. It's just a bit further. Walk this way. "
Alrighty then. Now that that's cleared up, let's get the heck outta' Dodge, whaddaya' say?
C'mon. Walk this way. And don't forget to grab a handful of those passing answers on your way out this time. Go ahead. They've got plenty of 'em.
