I just yawned again. I've got to go read something else. . . .
Ha, I just woke up from slumber also. I must have yawned about 7 times reading this thread (No exaggeration).

I often yawn, especially when my girlfriend comes to stay, she makes me yawn all the time because she yawns lol. Strangely enough I really liked the description about us doing it to flash our teeth. Not because it's something we do to make us seem more threatening in certain situations, but just because it shows we still have animal instincts in us. I'm going to try this on my dog later, I wonder if he will yawn also.
