Jon Stewart Smashes John Cena With Chair, Stephen Amell Debuts at WWE SummerSlam (Video)

“Arrow” star tag-teams with Neville to take on Stardust

Jon Stewart took down the most difficult politicians with his intelligence and crushing wit during his 16 years on Comedy Central, but how would he handle a stadium full of WWE Superstars?

Fans found out on Sunday when the former “Daily Show” show host took the mic to welcome John Cena, Brock Lesnar, The Undertaker, Sheamus, The Miz, WWE Divas, the Bella Twins and some of the biggest names in the WWE for SummerSlam at the Barclays Center in Brooklyn, New York, and TheWrap was there taking in all the action.

“No sleep till Brooklyn!” Stewart announced to the screaming crowd, invoking the Beastie Boys, before telling them, “I’ve spent the last 16 years writing about politics, it’s nice to be back in reality.”

Stewart announced his determination to take his Lesnar down following the wrestler’s recent defeat of the Undertaker. “Obviously as a small weak man, I would need a little back up,” he said, so he invited Mike Foley out to defend him. In a backstage video clip, Stewart crept down to Lesnar’s dressing room and got in an argument the wrestler’s manager, Paul Heyman, who told him: “I guess they couldn’t get David Letterman to host the show.”

Coming off a broken nose a few weeks ago, Cena was back with a vengeance against Seth Rollins for the main title of World Heavyweight champion. Cena, the man fans love to hate, sparked boos and a polite chant of “Please retire” as he entered the ring.

The epic battle even ended up knocking out the referee. But the surprise of the night came when Stewart jumped into the ring to whack Cena with a chair — then very quickly sprint back to safety — as he helped Rollins clinch the title.

Earlier, “Arrow” actor Stephen Amell made his highly anticipated WWE debut — doing his own stunts. The CW star and WWE veteran Neville tag-teamed against Stardust, who got into a fight with the actor a few weeks ago at WWE Raw.

Amell kicked it off with a flying leap into the ring, slamming his painted-faced enemy to the mat. The actor proved himself to be impressively athletic as he jumped over Neville’s head when he was tagged in.

Later, he was dropped from a great height by Stardust, but when it looked like he was out for the count, Amell made a surprising recovery and got the first standing ovation of the night when he leapt from the ropes to help score a victory.

However, the match-up everyone — including Stewart — was waiting for came between Lesnar and The Undertaker, who made an epic entrance complete with roaring flames and his signature funeral march.

A bleeding head wound from smashing a media table over his head couldn’t slow Lesnar down, who later gave the ref the finger right before being beaten by submission.

Saturday’s show focused on the up-and-coming stars of NXT such as Mojo Rawley and Zack Ryder, as well as the four finalists of WWE’s latest reality show, “Tough Enough.”

Former Green Bay Packers defensive end and “Tough Enough” favorite Josh Bredl is learning just how different the WWE is compared to the NFL. “You never do anything like this until you do this, so it’s make or break. You either figure it out or you don’t, there’s nothing comparable,” he told TheWrap. “You need that big energy [from football] but then you have to refocus it and break out of your shell otherwise you don’t shine in the WWE.

On Friday, Cena celebrated his 500th Make A Wish with a special event with WWE Chief Brand Officer Stephanie McMahon. The WWE Superstar will achieve the landmark wish total when he spends time with Rocco, an eight-year-old from Queens, New York, battling leukemia, before WWE Monday Night Raw.

“There is no more humbling experience than a child who could ask for anything in the world asking to meet me,” Cena said. “I have faced some of the toughest Superstars in WWE history and I’ve never encountered more bravery or toughness than I see in each wish kid that I meet. It is inspiring to see the impact that granting wishes can have and I look forward to granting 500 more.”

Stewart will return tomorrow during “Monday Night Raw” at 8 p.m.on USA Network to explain his actions.
