Thanks to Steve Scott for sending this in:
After Raw went off the air last night, Triple H called out The Undertaker and challenged him to a match, saying there wasn't enough room for both of them on Raw. The two wrestled a short match until the Smackdown crew came out to attack both HHH and Undertaker. Both guys took out the Smackdown crew and Triple H hit his pedigree on all the guys and even the ref. He then turned around into a tombstone pile driver from Undertaker to end the show.
Also, on a funny note, maybe you couldn't tell on TV, but from the stands you could clearly see R-Truth exit the entrance ramp when the Macgruber explosion took place.
