Fart Interrupts City Council - Medina, Ohio

What does Roberts Rules of Order say about dealing with a member of the audience farting loud enough for everyone to hear? But was it real or some kind of teenaged prank?

Watch the video below, but first a little background from MSNBC:

Members of the Medina City Council didn't think they'd end up on TV after someone passed gas. The mayor and council members began to laugh and a council member called for a recess, because they all got the giggles. In the Plain Dealer, the mayor disputes the source, saying some kids in the crowd got bored and used a phone application for the sound effect.
