When the bus is parked it's mentioned that the pie stand closes at 5pm and that's only 20 minutes from now. A couple minutes later Jim and Dwight are on top of the bus and Jim's watch reads 2:55.
When Dwight comes back from the roof he's not wearing his jacket, yet he is once he jumps in the driver's seat.
When many of the colleagues are extending their hands and hi-fiving Jim in the bus, Jim misses Pete and instead slaps him in the face.
When Dwight stops the bus to pick up a hitchhiking Creed, you can see The Rocky Mountains through the windshield. While Scranton is near The Pocono Mountains, they are nowhere near that large.
19154 pies divided by 61 pies is 314 *without a unit*, because pies being both in the numerator and the denominator cancel each other.
The line would make more sense used like: "19154 pies divided by 61 pies per person is 314 persons".
