Bubba's quirks

As Bubba approaches 1 year I have noticed lots of little quirks and habits that he has:
1) Bubba likes to carry his leash in his mouth to and from the elevator. It's almost as if he doesn't want to leave it behind, despite the, fact that it's clipped to his collar.
2) After every walk, even if he's tired, he'll sprint back and forth in the hallway before he's ready to come back in.
3) When Bubba gets a new treat or toy he'll tease it with a bouncing hopping dance, darting and nipping and jumping back before taking hold of it.
4) He loves to look out the window (more so at my parents' place) and watch dogs, people, squirrels. One night I saw him staring at a small set of lights in the sky (plane on landing approach). He was standing up on his hind legs on my bed watching the plane in the distance pass by window.
5) No matter how big or small, Bubba will pick up a stick as long as he can put it in his mouth and carry it home with his tail up high and proud for all to see. Some of his sticks have been too wide/long for him to get it through the door, but he'll try and try until it fits! Yes, I've watched him and not helped him... mostly out of curiosity to see if he can do it.
