Keanu Reeves took on the role of magician’s assistant on Wednesday’s episode of The Tonight Show Starring Jimmy Fallon on NBC.

The 59-year-old actor, who recently had his home burglarized, was recruited by master illusionist David Blaine, 50, to help him out with a dangerous stunt that he performed while promoting his upcoming magic shows in Las Vegas.

Reeves was on the talk show to perform with his band Dogstar, but Fallon, 49, also invited them to participate in magic with Blaine along with Questlove and Tariq Trotter from house band The Roots.

‘It’s not going to be too crazy,’ Blaine promised.

He first cut off a piece of thread and swallowed it as Questlove started to freak out.

Blaine said he was going to try and have the thread come back up and then pulled down his shirt revealing the tip of the thread sticking out from his chest.

Questlove pulled the thread from his chest and then Blaine swallowed it again. Blaine then had Reeves pull the thread from the bottom of his chin through his lower lip.

‘You have to make sure get it between the teeth,’ Reeves said while pulling the thread through.

Blaine moved onto a card trick that involved Fallon stabbing a card with a knife that matched the card Reeves picked from a separate deck.

‘You didn’t think actually think that I brought a knife just to do a card stab?,’ Blaine said afterward.

Blaine asked Reeves to check the sharpness of the serrated knife and he confirmed it was real.

‘This is a thing I’ve been playing with,’ Blaine said as he shoved the knife up his right nostril.

‘That is insane. That is serrated, by the way,’ Fallon said.

‘Will you do the honors?,’ Blaine asked Reeves.

Reeves then slowly pulled the knife out and Blaine used the knife to stab the table.

Dogstar featuring Reeves on guitar later played their song Blonde

Timothée Chalamet, 27, also was on the talk show to promote his new film Wonka

Dogstar after a commercial break returned and played Blonde from their album ‘Somewhere Between the Power Lines and Palm Trees’.

Blaine will be performing at the Wynn in Las Vegas and he said he devised the shows where anything can happen and no two shows are ever the same.

‘It’s very interactive, but at the same time there is a little bit of danger mixed in,’ Blaine said.

Timothée Chalamet, 27, also was on the talk show to promote his new film Wonka.

Fallon, who was accused of creating a ‘toxic work environment’ in a September article by Rolling Stone, has been host of the NBC talk show since 2014.
