If the walls had ears

I had a silly thought today...what if the walls had ears? I was walking down an empty corridor at work when I suddenly let one rip, a fart that is...I laughed to myself. Why does it feel good to pass wind, out loud that is!? I can only do it out loud when no one is around, but what if the walls have ears? I guess hearing it is not so bad, its if they had a nose...then that would be a bummer. lol!
