We don't know if this counts as the "biggest prank ever," but Jimmy Kimmel's interactive stunt during the 64th Primetime Emmys worked pretty well, sparking as many as 25,000 tweets, according to @TwitterTV, a feed that tracks tweets about television. (It was not immediately known how many Facebook posts it yielded.)

During Sunday's ceremony, host Kimmel recruited 30 Rock star Tracy Morgan to lie down onstage and asked audience members to tweet and post to Facebook "OMG Tracy Morgan just passed out onstage at the #Emmys. Turn on ABC now."

According to Mashable, the phrase "OMG Tracy Morgan" became trending worldwide on Twitter almost instantly.
