Two random things I've been wondering:
 
1.  What are the origins of pressing the palms of one's hands together to signify prayer?  I know that this gesture exists in xianity and in yoga, so it can't be religion-specific...
 
2.  I read that they film five episodes of Jeopardy! in one day.  Has anyone noticed if the returning contestant (or Alex Trebeck) wear the same outfit for two episodes in a row?
