The threads might be stripped. What are solutions to this problem? The other spark plugs came out just fine.

you will have to excorsize little patience,and spray some WD-40 on threading. you will have to wait for it work its magic(a couple of hours). spray it on threading and take in a movie or something. now it still will not come out easy but it will come out.
remember to coat threading on replacements with never seize prior to install. good luck.
