This should work:

$('#txt')
    .focusin(function() {
        if ( this.value == 'Write something...' ) {
            this.value = '';    
        }
    })
    .focusout(function() {
        if ( this.value == '' ) {
            this.value = 'Write something...';    
        }
});

Update:

This should do it:

$('#txt')
    .each(function() {
        $(this).data('default', this.value);
    })
    .focusin(function() {
        if ( this.value == $(this).data('default') ) {
            this.value = '';    
        }
    })
    .focusout(function() {
        if ( this.value == '' ) {
            this.value = $(this).data('default');    
        }
});
