Removing stuborn spark plug

I'm going through emissions on my truck tomorrow so I thought I'd change the plugs, all came out fine, but #2. The more I tried to lossen the plug that harder it got, so I only replaced three. Any ideas on what to do?

PS, I used plenty of antiseez on the new ones.


PS, so far I'm into the truck $218 total, $100 or truck with blowen motor, $100 for a runner with front end damage and $18 for assorted gaskets and such. So, I don't want a $1.50 plug screw this all up.

start the truck and run it till its hot, then give'er again,, it seems to work for me

just watch your fingers cause its hot. but thats what i do too
