Crowning Music of Awesome: The "shifty" song with the bell in The Tunnel has a nice vibe to it. It's the one that plays as they explore the back tunnel. It even picks up pace when Mike does making it very appropriate.
Also from The Tunnel. Dave and Mike decide to go into a dark, creepy, and unexplored tunnel to rescue a guy screaming for help. This despite the fact they can't call for backup, they know there's some creepy 'something' prowling around, the tunnel itself is a maze, and Dave won't use his flashlight. Dave and Mike don't even seem to be afraid.
