Pleonastic Acronyms

Speaking of redundant pleonasms (get it?), here are a few common ones that I notice on a regular basis. They are all evidence that folks don't understand the acronym they are using:

ATM machine (automated teller machine machine)
PIN number (personal identification number number)
SAT test (formerly the Scholastic Aptitude Test, or Student Achievement Test test)

[Technically, SAT test isn't a redundancy anymore. Early in the 90s the College Board decided that SAT no longer stands for anything. Too much grief from various sides of the political correctness debate.]

10% APR (ten percent annual percentage rage)
AC current (alternating current current)
DMZ zone (demilitarized zone zone)
DOS operating system (disk operating system operating system)
HIV virus (Human Immunodeficiency Virus virus)
LCD display (liquid crystal display display)
please RSVP (plese respondez s'il vous plait--please reply please)

Any I missed?
