In the episode when they got Bear the dog, it was established that he only understood Dutch commands. In subsequent episodes, they stuck to this. But in this episode, when John plays fetch with Bear, he uses the English commands "Sit! Out!" Dutch for "sit" is "zit," which sounds like "sit." Apparently, John tells Bear to drop the ball by saying "out," because in Dutch it is "uit," which sounds like a cross between "at" and "out."
Simmons receives a call on his cell from an unknown number and when the smartphone screen is shown, it has a "slide to answer" bar, similar to an iPhone. When the view switches back to him answering the call, it shows him pressing a button and a beep sound is heard, similar to that of an older style cell phone.
