Sounds like he might just be a mama's boy!
I've heard that for some reason, dogs often may bond more closely with an opposite sex owner. This seems to be true in my home, Nico is definitely "my" dog, while Sasha is right by hubby's side when he's home, despite that I do all the training, feeding, most of the playing, grooming, etc. DH is clearly a pack leader and enforces the rules along with me, but he mostly just plays with the dogs. Ruger hasn't met him yet as DH is away in the Marines until a short visit in May, but I have a strong feeling he'll still be a mama's boy right along with Nico.
Another thought, are you an excitable, energetic person, or more so than your husband at least? I think that can really rub off on a dog. Sasha's foster was a trainer, who despite doing things right with Sasha for helping her anxiety and aggression issues, was still having problems. It only took a week or so with me to see a huge improvement in her anxiety, so Jessi (trainer/foster) and I talked about it, and we realized that we do have very different personalities. She is very energetic, on-the-go, a bit anxious, etc. while I am very calm, relaxed, go with the flow, never get too emotional, etc. Sasha is a totally different dog now and you'd never think she was the nutcase she used to be.
I really think dogs pick up on our moods/personalities and may feed off that, so he might just be excited that you are excited. Also, do you react more to him when he does these behaviors? For instance, do you make more of a fuss while hubby ignores him blissfully watching tv? Otis just might be getting more fun out of you!
