Piston Slap: It's Not You, Drain Plug…it's Me?

Dear Sajeev,
I have terrible luck with oil drain plugs. Of the last 4 oil changes I’ve done, only one has been successfully completed in a single day, because I can never get the drain plug loose.
The culprits in these comedies of errors are a 1999 Saab 9-3 and a 2006 Honda Pilot. The first time I came across the stuck plugs, the Saab was a recent acquisition, and the Pilot had had its last oil change done at a local mechanic’s shop down the road. Therefore, I assumed that an overzealous shop jock who got trigger happy with an air gun was to blame. In the process of getting the plugs out, I managed to mangle the Saab’s bad enough to require the purchase of a new one, and should have also bought a new plug for the Pilot, too (but didn’t). When I reinstalled them, I put them in fairly snugly, but with the mindset that I didn’t want to get myself into this mess again.
