Not long ago, a teenager was arrested at Logan International Airport in Boston for what can only be described as a joke in poor taste. The teenager, you see, had seen fit to leave a profanity-laced note in his bag, which when found by TSA screeners, apparently caused no end of anxiety. Why? The note contained the word bomb.

Obviously there is a need for certain licenses. These are easy enough to spot. They typically make sense. Not just to you or me, but to darn near everyone. Things like a driver's license fit into this category. It's reasonably nice to think that the person headed down the freeway with you has at least some chance of being able to adequately operate their vehicle. Of course, that's not always the case - but generally it seems a pretty safe assumption. A similar licensing/qualification scheme for something like an airline pilot is useful. I think most will agree with this sort of thing.

Okay, folks, time for a pop quiz!

You'd like to see a movie this weekend, but find out that all the theater is playing are PG-13 and R-rated movies. What do you do? What do you do?

A. Skip the movie. You don't need to see such trash anyway. Rent a Disney flick instead.

B. Skip the movie, because you can't find a babysitter to watch your 4-year old, and, well, it's not really appropriate for a 4-year old to see those kinds of movies anyway.

C. Find a babysitter to take care of your 4-year old so you can enjoy the trash without worry of causing others distress or harming the poor kid with the contents of the movie.

D. Make sure you take your 4-year old to see the movie anyway, then get upset when either everyone complains about the racket or if you aren't allowed inside.

If you're like some people, it looks like the correct option is D.
