Drain plug won't budge

Peter H. wrote that some poor unfortunate soul had to use an air hammer (impact
wrench) to remove the drain plug.  That would've been me.

While trying to remove the plug for the first change after buying the car used:
wouldn't budge, wouldn't even think about looking like it was about to budge.  I
started using progressively larger and larger tools:  a wrench, a 3/8 drive
socket, 1/2 in, 1/2 in with cheater bar, etc.  All I succeeded in doing was
rounding the corners on the plug.

Using the "bigger hammer" theory, I got the air hammer out and removed it.
After reinstalling the plug, I went to the dealer and got a new drain plug which
lived in my glove box until the next oil change.  Save yourself the trouble and
have a new plug standing by in the event you have to do something silly to get
your old plug out.  

BTW:  This plug is BIG.  The threaded section is approx 1 inch diameter.  Do not
be fooled by a skinny little bolt head.  It's also a Porsche part.  My
replacement plug came in a little plastic bag with the P*** word all over it.
