It didn't look as though creator Shonda Rhimes would be able to top last week's twisty episode, when Meredith and Derek gave their wedding day to Izzie and Alex. Now I am ashamed I ever doubted her. The two-hour finale dragged at times, but Katharine Heigl, Jessica Capshaw, Sandra Oh, Justin Chambers and Chandra Wilson all got the kinds of Big Moments that pay off at the Emmys.

And the last five minutes? Truly gasp-worthy.

Read on for spoilers...

This website, about the (fictional) upcoming nuptials of Meredith (Ellen Pompeo) and Derek (Patrick Dempsey), got 1,400 RSVP's in the first 24 hours. Of course I went directly to the gift registry information... and found that they want you to donate your money to charity in lieu of gifts. C'mon, who doesn't need another set of candlesticks?

It was creator Shonda Rhimes' idea to market the show this way. Not surprising, since her sister works for celebrity wedding planner Mindy Weiss.
