I had quite a chuckle reading the blogs on this Farmer's Insurance advertisement. I didn't see the advertisement before, so this is my first time being aware of it. But still, I wish I had seen it.
I suppose the biggest blunder in the figure is that the symbol "s" was used as distance, yet in the figure, the various values of "s" were given units of "m/s". So that certainly is a rather dubious mistake.
The other part where the trajectory of the pig (cow?) is not quite parabolic, that I'm not that picky about (you should read the link above and see how this is analyzed in detail). A sketch on a blackboard is often "not to scale" or highly accurate (look at the asymmetric roof line on the house).
