Former “The Daily Show” host Jon Stewart decided to interfere in John Cena’s match vs. Seth Rollins on Sunday night at SummerSlam. Stewart, who served as the celebrity host of SummerSlam, hit Cena with a chair to help Rollins win the United States championship.

Monday night on “WWE Raw,” Stewart explained why he turned heel. He didn’t want to witness Cena tying Ric Flair’s record of 16 world championships. Flair then came to the ring to talk with Stewart, saying he would be proud to have Cena tie or break his record.

And then Cena arrived, and Stewart didn’t enjoy what happened next. Cena hit him with his finishing move, the Attitude Adjustment.

Points to Stewart for selling it like a champ at age 52.
