Billy makes it to the school and is seated in class when Marmaduke passes by outside even though he pushed Marmaduke ahead of the bus and Marmaduke should have made it to the school first.
Barbie: (reading the paper) Marmaduke is a hero!
Phil: Can someone tell me how you get a heroic dog off the sofa?
Billy: Good boy, Marm. You're a champ.
(Marmaduke barks and all the animals stop running around)
Teacher: Now there's a voice of authority.
Teacher: Now children. Who can tell me the name of our sixteenth president?
(Marmaduke roller skates by the window)
Teacher: President Marmaduke?
Motorcycle Cop: (catches up to a dressed up Marmaduke riding roller skates) All right lady, pull over. (he sees Marmaduke's face) Forget it lady. With a face like that, you have enough troubles.
Barbie: What genius! I hope it runs in our family.
Phil: Hey, Mr. Snider! I fixed your loose board.
Snider: I ought to fix your loose head.
