What better way to do it than by watching William Shatners Mysteries of the Gods ( Pt. 1, Pt. 2, Pt. 3, Pt. 4, Pt. 5, Pt. 6, Pt. 7, Pt. 8, Pt. 9, Pt. 10)(MULTI LINK YOUTUBE SHATNERFEST)

TV's Mythbusters, (and as such Metafilter's 'very own' asavage), hopes to use the global reach of Youtube to send a yawn around the world. "If only one per cent of the global population took part in the Yawn Around The World experiment then 65 million people would have yawned across the globe" Savage was quoted as saying. The equivalent amount of air exhaled would "be able raise the Titanic or even inflate all the bicycle tyres in Beijing." Fascinating stuff! Watch the (hopefully) yawn inducing footage here.
