Passing Gas Isn't Funny When it Comes to Smoking

When discussing the art of passing gas, humor is usually right around the corner. In this new spot from the American Legacy Foundation's long-running Don't Pass Gas campiagn, however, humor isn't in play. The passed gas that's being discussed here is hydrogen cyanide which is said to be found in second hand gas...uh...smoke. Perhaps Flatulina would have commentary on this.
