Sink plug jammed, how to go about fixing it?

House_owner

Get some strong tape --duck tape or gorilla tape. Wrap a length around your knuckles,sticky side out. Press your fist against the stuck plug, and pull. This worked in my house!

I think as others have said ,change it for a new one as it looks like it is shot ,why have the same problem again in a few days /weeks.

Popped it off by using a metal hanger under the trap.  Going to get a new sink anyway, as we just moved in and was making sure everything works as it should.  Least I can use the bathroom now!  Thanks for all the advice.
