There's a guy who lives roughly in my neighborhood who is like that. (not the hopping around on hind legs like a dog....)
I've seen him walking around with a cell phone balanced on one shoulder and a cup of coffee in his teeth (or lips). He'll go along sipping from his coffee, tipping it up with his lips, and occasionally flip the cell phone over by shrugging one shoulder and rolling it with his neck. I've seen him shift the cell phone from one shoulder to the other as he was walking just by shrugging.
I don't want to think of how he dials the damned thing though.
I've also seen him walking back from a store with a package balanced on one shoulder, his cell phone on the other, and a big gulp in his teeth.
No arms must suck.

Ride it like you think owning it matters.
