There's a fun discussion on the bad physics in a TV commercial.
One can argue on what is the big deal about something like this. After all, we see bad physics in TV and movies very often. Well, this isn't a big deal at all. It is just a fun exercise, even for students, to practice their knowledge on simple kinematics. But on the other hand, considering that physics-based games such as Angry Birds, Where's My Water, etc. are trying to get as close to being physics-accurate, there's very little reason (other than pure fiction or pure fantasy) to completely blow away all kinds of reality.
