Dear John McCain,

For the third and hopefully the last time, IT ISN'T AN OVERHEAD PROJECTOR.

This is an overhead projector. It's useful for projecting transparencies, and has lately been replaced by digital projectors. It's useful for presenting pie charts.



You can pick one of these up at OfficeMax. It'll set you back $200.

This is a Zeiss Mark 9 planetarium projector. It's a multi-lensed projector that can display fully accurate high definition video of stellar objects over a 180 degree hemisphere. It's involved in what is often a child's first full fledged science experience.



These will set you back a few million dollars, because it ISN'T A FUCKING OVERHEAD PROJECTOR. PLEASE STOP CALLING IT THAT.

I hope that clears up the confusion you seem to have.
