Graham's cracker

My favorite thing that happened today:
I was throwing a ball back and forth with Graham, which puts him out of his mind with glee.  He squeals, thrusts out his arms, and stomp-runs to chase it.  After one toss of mine he chased it, and  passed over a graham cracker he'd abandoned on the floor earlier.  A few steps from there, he squealed again, ran back to the cracker, the same jubilant edge, and shoved it into his mouth. 
And then he lumbered over and collapsed in my arms.
He's one of my unending obsessions.
