Jack's Secret Life

I sometimes wonder about the time that Jack spends every week with Margarita.  Where do they go?  What do they do?  We get an update every evening, but it's pretty bare-bones:  which park, how much food and sleep.  But what does he really do?  Is he playing with cars or on slides, like we see on the weekends, or is there more to it?  Margarita's picture this morning reveals that it's much richer than we've imagined.  
Of course, this just inspires more questions.  What are the best clown colleges?  Does his Montessori school have a good plate-spinning program?  Where do you get clown shoes for feet that small?
