Had a spot on the top of my shoulder the other day & decided to tackle it the only sensible way possible - pop that bastard. I've been struggling with an unpoppable zit on my cheek & was concerned this was the same, so left it for a couple of days. Then it became clear that it was going to bear fruit.
Placed myself in front of the mirror where I could see what I was doing, grabbed said zit between forefinger and thumb, and gave it a good squeeze. The results actually hit the mirror so hard I heard the thump. It was great.
