When the three men are in the park, and the police show up, Eddie is shown with one hand holding his coat with Bink underneath. However, when we get a look under the coat, both hands are shown underneath.
When Eddie, Norby, and Veeko first notice Baby Bink on the bus and run toward their van to chase after him, Eddie's hair is all messed up and it and his face are still covered in bird seed, etc. from when he fell off the building. In the next scene, when they are driving after the bus, he's perfectly clean.
