Never throw away that intro Dave. It somehow creates a small grin on my face while seeing it, knowing that there was probably a bit of sarcasm involved while shooting it.

It’s painful watching a guy not be precise in counting his turns in and messing up the settings on the way back out. Not that we know they were right to begin with!

That's just a demonstration. Dave's the one that's doing the tuning with precise settings.
