This can be handy, no doubt. I have a monitor that flips out blinking if you knock the cord, which my cat has seen fit to do a couple of times.

Don't forget the mnemonic - Raising Elephants Is So Utterly Boring.

There are a couple of variations:

REISUO will shutdown rather than reboot.

Some prefer RSEIUB, syncing earlier in the process - aka Rasing Skinny Elephants Is Unusually Bland. You may wish to throw another Sync in there to make RSEISUB.

I still prefer the mnemonic "Reboot Even If System Utterly Broken", plus it describes what it does. :)
