“America’s Got Talent” Season 11 judge Simon Cowell was at a loss for words during Tuesday night’s semifinals after he was called to the stage by the hilarious jugglers, The Passing Zone.

Jon Wee and Owen Morse opened their act with hilarious banter. They also thanked the three judges who invited them back as a wild card contestant despite having already been eliminated two weeks ago. Upon reaching the stage, the duo instructed Cowell to stand very still because what they were about to do was quite dangerous. They also made him wear a helmet with an antenna and asked him to hold two sticks, which made him look like the devil.

During their routine, Wee and Morse threw several pieces of flaming torches in front of Cowell. By the looks of it, the torches were thrown very close to the judge’s face, which made Cowell visibly nervous and worried during the entire routine. Luckily, The Passing Zone was able to complete their act successfully, thus receiving thunderous applause from the audience, Mel B, Howie Mandel and Heidi Klum.

Meanwhile, other acts that appeared on the hit NBC reality competition included singers Jayna Brown, Justin Brian Crum, Calysta Bevier and Kadie Lynn. Magicians Kadan Bart Rockett and Steven Brundage also wowed the judge with another extraordinary Rubik’s Cube magic show. All-male singing group Linkin’ Bridge performed their own rendition of Lukas Graham’s song “7 Years.” The Clairvoyants also impressed the judges by guessing what’s in their minds. Sofie Dassi and Viktor Kee also performed contortionist and juggling acts, respectively, according to Buddy TV.

The five acts that will make it through to the finals will be revealed on Wednesday, Sept. 7. According to NBC, there will be another Dunkin’ Save, and the judges will have to decide which one of the five acts will advance to the next round.

“America’s Got Talent” Season 11 airs Tuesdays and Wednesdays at 8 p.m. ET.
