I have shares of a stock that are completely worthless. I want to get rid of them, how do I do it?

These shares have been completely worthless since 2014. They aren't worth anything and aren't trading. I have had them so long that my shares have been tossed around through clearing house brokers. I can't sell them, they aren't even on pink sheets. I am tired of getting quarterly updates that they are all worth exactly $0. I don't even care about writing it off as a loss. I bought some stupid stock while I was in college for $100. How do I get rid of these shares??
