haha...bent pins...that happened to me once with my old P4 chip.
Before knowing the heat sink was stuck to the chip, I had already pulled the whole thing out, mind you w/o touching the lever, convinced I had fked the socket badly. I then proceeded to hammer the chip on the edges alongside the heat sink using a hammer and tiny flat-tipped screwdriver. I had to take the chip out cus I couldnt put it back in. So, 2 or 3 hard knocks the chip fell out and dropped down from the desk into my toolbox full of rusty nails and who knows what. At this point all hopes had ended. When I took the chip out most of the pins were bent. I then used my micro flat tipped screwdriver to properly align the pins. I prolly spent an hour aligning those pins but in the end with close precision the chip fit into the socket like a glove. Put the sink back on with new thermal paste, and to my amazement that p4 came back into life.
So the moral of the story is, if you think the sink is jammed, never pull it out. Prime95 your system for a bit then proceed my rotating the sink rather than pulling on it. Once you feel its nice and loose, slowly pull it out and you wont hurt the chip.
Now I got a amd 64 venice which I treat with great care. Its my little hoe.
