Do you need to "unwire" an anonymous function/lambda

My understanding is that any event handlers wired up in C# need to be unwired as such.

Object myObject = new Object();
myObject.Event += EventHandler; //Wired
myObject.Event -= EventHandler; //Unwired

But do you need to unwire the following code? and if so, how?

Object myObject = new Object();
myObject.Event += (object sender, EventArgs e) => { }; //Wired
myObject.Event -= ????? //Unwire? How?

My assumption is no?
