Maybe it was her Australian accent.

Rebel Wilson took on the Whisper Challenge on Wednesday’s Tonight Show, donning noise-canceling headphones and trying to guess random phrases whispered by Jimmy Fallon.

“What happens if you lose, do you need to strip?” she joked.

“Deflated balls,” was the first clue.

“My big box,” she guessed followed by “feel my balls,” which prompted Fallon to laugh. She tried again, but still couldn’t get it right.

Next it was Fallon’s turn to guess.

“Forklift driver,” the Pitch Perfect 2 star said. Then Fallon failed.

Wilson finally redeemed herself, by correctly guessing Wiz Khalifa.
