How to send ' .exe ' files in gmail

I've found a silly but interesting trick to send executable files ( .exe )in gmail.Sometimes it seems easy to send small executable files like flash,poke games etc,.But it rejects. So do the following. Just open folder options from your menu bar and then click on view tab.Make sure to un-check the option " Hide extensions for known file types ".Now rename the file with any extension other than .exe. That's it.You are done. Attach the file(which is renamed) and send it. But the receptor have to change the extension to .exe again to execute it.
Enjoy ......Have fun
