I think the most recent time Steve yawned was last weekend, when I actually happened to be around him during the early morning. Before that, I can't even remember!! During the week, I'm at work, and on the weekends, the tortoise mommy is making coffee in the mornings so she can function! And of course, I never have a camera handy, hehe.
Also this thread is making me want to yawn. XD Time for more coffee.
