I wish I could have gone with Stitch on a Field Trip

I'm really jealous of Stitch again.  So remember last week, Stitch got to meet Santa and 600 military kids?  Well, today, Christmas Day, Stitch got to go to the Hospital and cheer everyone up!  He has the best job in the world.  I want his job!  Look how happy Stitch looks in this photo with one of the nurses:

How do I get to do this?  I almost know how to sit already.  Maybe I just need to try a little harder and I can go next time.
