I just changed the plugs on my car, and I'd like you all to give them a quick visual analysis. They look OK to me based on the pictures I have seen on teh intartoobz, except for the insulators from cylinders 2 and 3.

The car is a '02 Pro with a 2.0L engine that just turned 110,000 miles. The plugs themselves have about 60K on them. The plugs are arranged left-to-right, cyl. 1-2-3-4.

This is the only one I have a big question about, cylinder 3. Brownish discoloration on the insulator, and a film of oil on the nut and washer. When I shined a light down the plug hole, there was a film of oil at the bottom. Not a lot of oil, just enough to make the bottom of the hole brown. The car does not burn oil at an alarming rate, probably 1 quart every 10000 miles.
