For many, this is an welcome diversion from the inanity that is occurring before them on the pitch, field, diamond, rink or pit. That the wave can occur relies on the likelihood that there is a large number of disinterested people, who are attentive enough of their surroundings to participate.

If these initial premises hold true, this is the potential breeding ground for the greatest collective yawn to have ever been created! The Stadium Yawn will have a similar 'yawn epicentre' as that of the wave. A group of stadium yawners attending a match ought to either rehearse a perfectly contagious yawn, or else spent the previous twenty-four hours without sleep.

Just as this group would have instigated a wave in tandem by standing and throwing their arms above their heads; they would persistently yawn from their seats, perhaps incorporating a lazy stretch into the mannerism. Whence successfully communicated, this devastating yawn will spread rapidly and perhaps indefinitely around the continuum.
