History is shaped by our hands.

I'm really getting sick of television previews.  I no longer watch "Next week on..." bits at the end of a show.  I also don't watch "Tonight on..." pieces at the top of a show.

"24" SPOILER ALERT:
Last night on "24", we saw the return of the former first-lady.  I did not need to see this in the preview.  When the former president says that he has an idea on how they might be able to overcome their current situation, it isn't a shocking surprise that he's going to leverage the former first-lady when I already know the former first-lady is going to be on the show.  When the preview for the show says that we are going to see the most shocking thing in the history of "24" tonight, I immediately start connecting dots, assuming who is going to be involved, and being on guard when these characters are on the screen.  I wasn't shocked or surprised at all when the former first-lady attempted to kill the former president.

These previews are getting out of hand.  I know the networks need to sell these shows to viewers, but let's try to do it without ruining the fun.
