Stewart turns heel; WWE SummerSlam ends in controversy

"Just when they think they got the answers, I change the questions." -- the late Roddy Piper
SummerSlam on Sunday night in Brooklyn wasn't meant to be a tribute to Piper. However, one could argue that the results were a subconscious homage to the WWE Hall of Famer.
First, Jon Stewart, fresh from 16 years as host of "The Daily Show," turned heel on John Cena. Yes, Stewart turned heel on Cena.
Stewart ran into the ring in what fans thought would be an attempt to save Cena from the villainous Seth Rollins.
However, Stewart fooled everyone and took the chair he brought with him and blasted Cena with it, leading to Rollins being victorious.
In the other feature match on the star-studded card, controversy ruled.
The Undertaker sought revenge against Brock Lesnar for his defeat in WrestleMania 30. However, the timekeeper thought he saw 'Taker tap out to a submission hold Lesnar had applied.
Ah, it is never that simple in the surreal world of WWE.
Referee Charles Robinson didn't see, ahem, The Undertaker tap out.
The Undertaker then landed a low blow to Lesnar, who recovered temporarily to shake off The Dead Man before passing out, leaving Undertaker with a dubious victory.
No doubt, this will set up a third and final confrontation at WrestleMania 32 in AT&T Stadium in Texas next year.
