These are awesome. Crazy, you were producing such quality clips even way back then.

As far as I know Scotty is a 1 man team, but if there are others involved, thank you for the work you've done. * Scotty thank you for the car computer reset tip! My Subaru 2010 Forester that has 364530 miles is still running with the same transmission but with 2 engine overhauls and it is almost due for timing belt replacement. I've cleaned my engine bay over this weekend disconnecting the battery and the engine would idle rough when the A/C engages. By resetting the computer according to your tip did the trick, thanks and keep on bringing your funny common knowledge videos!
