As Ken talks to Julie in the library, he puts down his yellow notebook, but as soon as Tom and his buddies arrive, its magically in his arm.

As Tom starts chasing Ken in the library, Mike carts a book cart in Tom's way, causing him to trip and the books to fall over, but when Tom gets up, the books are neatly stacked on the cart.

When "Ken" is describing where he previously lived, he pronounces "Salina, KS" with a long 'e' sound, which is how it is pronounced when describing "Salinas, CA". In KS, it's pronounced with a long 'i' sound.
