Is it sad that some of your "punishments" such as educating Steve and Thor on moder culture, baby sitting duty and escorting Jack Harkness around sounds like more fun than punishment?
They all sound fun, don't they? I have had crying agents come to me after being assigned to teach Mr. Odinson. They tend to forget he is the God of Thunder when they hand him their electronics.
Escorting Captain Harkness means ensuring he is productive and not coming onto everything that moves. Many agents find this habit amazing and tend to purposely pass by him. We are a very busy organization and we would prefer if our agents would do their duties instead of chasing him around. Because of this, most of the time spent escorting the Captain is really spent chasing away other employees in order to keep our organization running properly.
And no single person enjoys babysitters. I'm sure you all at least know the plot of Nanny McFee.
