Why do we yawn? And why are they contagious?

Bill Nye the Science Guy (one of my old favorites on Saturday Morning) attempts to answer the question of we yawn? Bill is with me on not buying this whole "because you need more oxygen" idea. That doesn't explain why I yawn when Bill Bob yawns - just because he needs oxygen doesn't mean I need more! So why?

walt, when you yawn, your body provides a quick boost in adrenaline. that's why you do it when your tired (and if your me, that's all the time...). word up.
