I don’t know why, but watching critter videos is always soothing to me: and they do come up with a lot of stunts that make me smile. Like rolling in thick, black mud. Pulling the toilet paper off the roll. What makes me smile is the fact that those are not my critters.
By the way, if the guy with the lizard understood basic lizard body language, he would realize that his Australian bearded lizard has taken a very strong dislike to that computer. That’s what those head-bobs mean.
