Sometimes you do strange stuff with your Linux PC.
I did yesterday, when I was experimenting with what would happen if I would chmod /usr/bin/chmod to 000. That gave me some problems. Solution from: Linux Magazine

If the CHMOD program is not executable anymore, you should start it via the linker.

Execute this command:

/lib/ld-linux.so.2 /bin/chmod 755 /bin/chmod 

This also works for other programs, just as long you know the original path to it...

Edit: 777 edited to 755,
Here is another solution thanks to: Rainer Weikusat

perl -e 'chmod(0755, "/bin/chmod")'
