Chase keeps running around the house singing a song he made up called "Eatsa Pizza:"
Eatsa,
Pizza,
Now...I gotta eat a pizza...
Pepperoni eatsa pizza...
[repeat ad infinitum]
The recording is kinda scratchy, but you can hear it here. This will no doubt be a follow-up hit to that old Rackham favorite his mother sang as a child:
Poooor doggie,
I will feed you...
[repeat]
