I'm Your Pushergran

I'm your granny, when in need
Some graham crackers I will feed
You know me, I'm your gran
Cracker feeder thick and thin
I'm your pushergran
Ritzy crackers, yummy fool
Super tasty, super cool
Tastin' good for the man
Nabisco, here I stand
Who needs to eat leavened bread
Cracker crumbs in the bed
I'm your pushergran
