OK, I think these belong on your list:

Fishermen who drive Escalades, Mercedes or BMW SUVs.

Hey Aunty, yea for any fisherman who styles his hair, but ya' gotta' consider that all those Renton/Kent fishermen who wear their plastic ball caps backwards are required by city ordinance to have wives/girlfriends who blow dry and spray to meet the "big hair" city code (circa old "Almost Live" comedy routine).

And you realize, don't you, that a tune up has devolved into just changing the spark plugs? It's been a mighty long time since I had a rig that had points, condenser, etc., or that I had to adjust the timing on. So it's entirely possible that some of our younger, non dip-sh!ts haven't even seen a car or truck that has those parts.
