Super Freak
Hot water, lots of trying to squeeze the tweezers in, and lots of pain and suffering later: I finally got the peg out. Look at the size of this thing! Never again
I find the best way to remove a broken peg that's lodged in a socket is to take a very small and long pointed screw and screw that into the broken peg enough that the screw threads grip into the plastic peg and then pull the screw out with pliers along with the broken peg. It also helps to make a small pilot hole into the peg using a drill bit in a pin vice so you don't have to apply too much force trying to drill the screw in by it's self.
You'll have less frustration that way.
