Funny. (you probably know this but) The cartoon isn't about if batteries are more dangerous than water bottles or even a jab on the TSA policies about grading the danger of stuff, it's about how nerds will dig their own graves because it's on our nature to point flaws, to improve a system/process, and how detached from the way relationships work (specially these of power, like employer/employee) we can be. In other words, how reason and logic tramples everything else.

At least this is how the cartoon resonated with me.

But hey, we all look at our own bellies.
