// Did you mean return false?

// 'return false' stops the default behavior of the event 
// and prevents it from bubbling up DOM, which kills 
// event delegation and may not be what you indented.
// Learn how these event methods can fine tune your
// event handler functions. 

$("#clickme").click(function(e) {
    //Prevent the default click action from firing.
    e.preventDefault();
    //Prevent the event to propagate up the DOM tree
    e.stopPropagation();
    //Kill all default behavior and event propagation. (not recommended)
    return false;
