'The Oprah Winfrey Show' Ends, Christopher Meloni Exits 'SVU' And Much More In Today's Twitter-Wood

OprahToday's a day for saying goodbye in the mysterious land of Twitter-Wood. (Not for us, mind you — we're not going anywhere!) The Oprah Winfrey Show comes to an end today after 25 seasons on the air, and while many people across the globe are mourning the show's conclusion, many stars and celebs are marking the occasion with their tongue firmly in cheek.

Meanwhile, longtime "Law & Order: SVU" actor Christopher Meloni is reportedly exiting the show, leaving his fans (and some of his colleagues) in shock. But the saddest and most surprising news of all is the death of CNBC news anchor Mark Haines, who passed away unexpectedly at his home yesterday evening; his loss is marked in today's Twitter-Wood as well.

But there's happier news today, too. Two more people have discovered the awesome power of "Bridesmaids," while the long-awaited "American Reunion" finally enters production, with Stifler's mom firmly in tow.

I'm @roundhoward and this is Twitter-Wood for May 25, 2011.
