I think, Alexis, that your dad had a great sense of humor because he made a funny pose. He was relaxed enough to be goofy. My dad's funny photos are him in a funny location or wearing a funny outfit. But posing, he couldn't do what your dad did in this photo, so I think he was a serious person at heart, perhaps more like your mom. But I would do the goofy poses and he'd laugh. Like you, I find a lot of things funny.
