Removing file named -rf in Unix

I did something crazy at some point that created a file called “-rf” on my filesystem. Now I can't figure out how to delete it.

I've tried:

rm "-rf"

rm -rf

But these just exit immediately. Arrgh!

Anyone know how to remove this file? Preferably without accidentally cleaning out my whole folder.

heh. What're the odds, eh?
