Whenever this card came from, I'm printing out one and placing it on my desk from now on.

At least they're being frank about it.

Common sense is really like a deodorant. The people who need it the most just won't use it...

It's really sad but common sense indeed is very rare and... the people who need it the most just don't use it.

Now that's pure wisdom... That's true common sense. Walk away from stupidity and the World becomes a better place. YUP!

Indeed, common sense is like deodorant. The people who need it most never use it.
