Arnold Schwarzenegger, Jimmy Fallon Share One Brain in Johnny Carson-Inspired Segment (Video)

“Terminator: Genisys” star and “Tonight Show” host face off on “Brainstorm,” recalling Carnac the Magnificent

Arnold Schwarzenegger and Jimmy Fallon gave us a throwback to Johnny Carson’s Carnac the Magnificent segments on Wednesday’s “Tonight Show.”

In a segment called Brainstorm, the “Terminator: Genisys” star’s brain was attached to the late-night host’s via specially-made dual headbands. Schwarzenegger provided the answers, while Fallon had to then telepathically guess the question.

“It’s complicated,” Schwarzenegger began. Fallon responded, “How does Rachel Dolezal describe her ethnicity on Facebook?”

The pair also got political, with Schwarzenegger delivering his iconic line, “I’ll be back.” To which, Fallon said, “What does Chris Christie say after leaving a buffet table?”

Both men struggled to keep it together during the bit, with both of them trying their best to hold back fits of laughter in between answers and questions.

The highlight was the answer to Schwarzenegger clue “Carly Fiorina.”
