Simon Cowell and Howie Mandel’s hilarious prank on unsuspecting 'AGT' fans

As America's Got Talent viewers waited to find out the next two acts moving on to the finals, judges Howie Mandel and Simon Cowell decided to go check out the America's Got Talent Las Vegas Live venue at the Luxor Hotel and, while there, had a little bit of fun with some unsuspecting fans.

Pranks on AGT are kind of a tradition at this point. Last year, Simon pulled one on Sofia Vergara when he pretended like he was accidentally shot by an arrow. Later in the season, Sofia got her revenge on him by having an embarrassingly hideous bust of him made, and who could forget just two months ago when the Bella Twins pretended to be creepy cosplaying contestants fighting on stage after their audition went sideways. However, on Wednesday, it was Howie who almost got in a fight when he messed with a couple of guests attending the show's VIP experience.

Behind the scenes, Simon was speaking into Howie's earpiece telling him what to say. Disguised in a short blonde wig, glasses and a face mask, Howie asked the man and woman to prove that they were "important people" in order to be there. "I would imagine they're below the level of importance that we're going to use for the promos?" asked Howie. The woman stated, "This is really coming across really rude."

Simon was having the best time laughing at Howie as he stated, "My job is to get him punched."

"You're going to get me killed! Oh my God, I've never sweated this much in my life. I thought it'd be a fun day of pranks. He's going to get me killed," said Howie.

Ultimately, the guests were surprised to learn that it was Simon and Howie playing with them the entire time. And the surprised reactions didn't stop there. Later in the episode, AGT viewers were shocked when ventriloquist Celia Munoz, who made a big impression Tuesday night with her tribute to Olivia Newton-John, was sadly eliminated.
