American Dad sighting

On the Fox cartoon American Dad, Dad was going into a secret Area 51 type lab, and says, mmI'll check in this room with the theremin playing, guess what was playing on the sound track...

ive seen this episode!

Is that show produced or written by the same people who do the Simpsons? This is at least the 3rd cartoon I've heard of that includes a theremin in the storyline (Simpsons, the one on Nickelodean about the ape - forget the name), and now this. It's great! I love to see the theremin working its way into the subconscious of pop culture.
