Hugh Jackman and Shaquille O’Neal played a game of “Phone Booth” while appearing as guests on The Tonight Show Starring Jimmy Fallon.

Phone Booth On ‘Tonight Show’

Host Jimmy Fallon had Shaq and Jackman get into their respective phone booths Monday night before firing off a series of questions. For each wrong answer, a new person would be added to the phone booth. Likewise, for each right answer, a person would be added to the opponent’s phone booth.

First up was Jackman, who was asked where saunas were invented. Correctly guessing Finland, Jackman’s answer saw Shaq get Jeopardy‘s Alex Trebek as his first booth mate. When Shaq answered correctly that the femur is the longest bone in the human body, Jackman was joined by a Blue Man Group member.

Jackman, after answering that Jupiter is the largest planet in the solar system, sent The Blacklist actress Megan Boone to join Shaq and Trebek. And since Shaq and his new friends couldn’t name all the Spice Girls’ nicknames, chef Elan Hall got inside the phone booth with them.

Australian native Jackman then delivered the final blow to Shaq, getting it right that the White House is on the back of a USD $20 bill and sending Property Brothers stars Jonathan and Drew Scott – as well as the Mr. Mets mascot over to Shaq’s phone booth.

Jackman had appeared on The Tonight Show to promote Joe Wright‘s Pan, while Shaq was a guest on the late night program to hype his guest appearance on sitcom Fresh Off the Boat.
