Why does old worthless Enron stock still show up in my brokerage account?

It's displayed as "293561106", the CUSIP number of the old Enron stock, see here http://ift.tt/2iGGvKR

300 shares with a Market Value of $0.00.

It's kind of a nice reminder of my poor investment decisions, but 15+ years later it's just kind of odd to see it still there in the account. Why do they bother?
