That picture made my day! Toooooo funny!
When I'm on the computer, Higgins brings me toys, then gives me a "YO, Momma!" bark so I'll notice him. I then tell him that I am busy and I don't like his "Yo Mommas" and to go ask his daddy to play. That is good for about 3 minutes of peace until Don has gone through the routine. Then Higgins comes back and silently SITS UP and begs and stares at me. It works every time. I then toss whatever he wants to fetch a few times and then tell him I have to go back to my "work" and I'm good to go for another five minutes while he is working on Don.
