John McCluskey pleaded not guilty today to second-degree harassment charges for his Hamptons altercation with Rudy Giuliani this weekend, but did go ahead and sign an order of protection saying that he would leave Giuliani and wife Judith Nathan alone. McCluskey did not bring a lawyer to court today, telling reporters, "Why would I dignify this with a lawyer? I think it's so frivolous." Both sides accuse the other of elevating the spat into physical threats—police reports say that when McCluskey was being taken away as he said to cops, "I didn't know that scumbag still has so much power out here...I have the right to speak my mind and tell him how evil he is...You all will regret this." McCluskey might have to think about dignifying the incident with a lawyer pretty soon—he'll need one to show up in his place at the next court date in June. He told a judge that he won't be there since he's leaving the country to film a documentary.
