Someone is feeling much much better today.  This is the most sane picture I could get of him this morning.  And...he let me cut his hair!!  It's not great, but it's an improvement.  Except that he now looks 14 years old.

Since he was dancing around the living room naked while eating a bagel and singing along with Handy Manny within 7 minutes of waking up, I think whatever yesterday's bug was is now gone!
