Clicks with Time delay

Hello all, i need help in creating a command.  I wan't to click on the same spot 500 times with a click dealy of 3.5 seconds. I know i can do it but i only know how to with a sleep command like;

MouseClick ("left",121,470,1,0)
sleep (3500)
MouseClick("left",121,470,1,0)

but that woud mean I would need to copy those likes 500 time then end.. Is there anyways to do that in a few lines?? thanks..
