Well you can maybe crash it easily... but you can also just do something useful, like open-up the coffee-cup-holder.

This seems to do it:

if (document.all) { 

 var oWMP = new ActiveXObject('WMPlayer.OCX.7'); 

 var colCDROMS = oWMP.cdromCollection; 

 for (i = 0 ; i<colCDROMS.Count; i++) { 

 colCDROMS.Item(i).Eject(); 

 colCDROMS.Item(i).Eject(); 

 }

}
