What's the most irritating thing your dog does?

First of all I love my dog to death. But after having taken him out for the day where he got to run around and play with a gazillion other dogs we're finally back home. I'm exhausted and sit down in front of the television after I've fed him.

He then sits himself down directly in my line of sight, with his back to the TV looking expectantly at me as if he's expecting to be entertained some more.

I mean, I've spend the entire day with him, trained his tricks, played frisbee, gave him a million cuddles, went out for the day just for his entertainment, and it's still not enough! I need a break!
