Heather McDonald collapses on stage

 It almost seems like part of the bit, but it appears it wasn’t.  You can clearly see her hit her head hard on stage.  Prat-falls aren’t like that.  It almost seems God has a sense of humor.  BTW, the crowd thought it was a bit.  The doctors don’t know why she collapsed.  Anyway, she does have some injuries, a skull fracture, but she seems to be okay.
