Grrrrrr (1) - I'm not sure I approve of this "snake" concept.
(Intent stare at Mark) - Don't you think you've slept long enough?
(Walk on Mark) - No, really, that's enough sleeping. We're going outside now.
Grrrrrr (2) - Look! There's another dog over in that driveway that we're walking near! Of all the nerve!
Woof woof woof woof! - I believe there's another dog somewhere outside your home, and I can't believe you're not as concerned about this issue as I am!
(Intent stare at speaker) - Dude! You have a TiVo! It makes the coolest bloops and bleeps!
