So silly you’ve got to laugh! Hugh Jackman was the latest celeb to play one of Jimmy Fallon‘s now-famous celebrity games on Monday, Oct. 5 — and evidently against his better judgment, Shaquille O’Neal got caught up in the fun too!

Jackman, 46, and O’Neal, 43, were both given their very own phone booths, and instructed by Fallon to step inside (no mean feat for the very large basketball legend!)

“When you get a question wrong, a stranger from the mystery bench gets shoved into your booth,” Fallon explained to his guests, showing them the silhouetted outlines of the celebrities in question.

First up was the Wolverine star, who impressively knew exactly which country had invented the sauna.

Thank You!

Fallon called out his mystery bench stranger, and Jeopardy!‘s Alex Trebek was tasked with squashing inside Shaq’s already-full phone booth!

The sporting legend then also got his question right, meaning Jackman was joined by a spooky (and totally mute) blue man from Blue Man Group.

Watch the whole funny video above to discover what happened when an extra five mystery guests were forced to squash inside one of the phone booths!
