This whoopee cushion orchestra is just one of the many ways UK charity Comic Relief is making the world a better place using fart noises.

Another is a project by acoustics professor Trevor Cox [ha.], whose website asks you to help identify the funniest whoopee cushion sound. Cox also designed the world's largest whoopee cushion, and British girl band The Saturdays sat on it. We love watching BBC types try to analyze the humor of the whoopee cushion, but what we're really interested in is this: how do you spell a fart noise? [BBC, Newslite, YouTube]
