Jack Black hosted this week's episode of Saturday Night Live (SNL), which honored him as he made it into the show's Five-Timers Club.

The 56-year-old comedian is the latest celebrity to join the exclusive cohort of stars who have hosted the show five times.  

For the milestone achievement, Black was ushered in with cameos from several famous faces.

Among them was former SNL regular Tina Fey, 55, Jonah Hill, 42, plus musical guest and fellow Five-Timer Jack White, 50.

After interrupting Black's monologue, Hill showed him to the Five-Timers lounge, which was eerily covered in spiderwebs – poking fun at how old the long-running sketch is.

Melissa McCarthy, 55, and Candice Bergen, 79, also appeared in the bit.

'You're the first Black in the Five-Timers Club,' Fey quipped after entering the scene to roaring applause.

She was clad in an SNL UK First-Timers jacket, complete with fur trim from the famous animated character Paddington Bear, who hung off the back.

That's when Bergen entered the fold with a joke: 'You know, I spent a night with Paddington back in '73. Let's just say he found something that he likes way more than marmalade.' 

McCarthy made her entrance as she popped up behind the bar and asked, 'Does anybody know where I can just get a drink? I can't find one.'

She took aim at SNL alum John Mulaney as she complained, 'All they've got are these warm cans of John Mulaney's beer,' to which Fey asks, 'Those are non-alcoholic though, right?'

'Not if you fill them with vodka,' McCarthy cracked before shotgunning the drink.   

'Desperate times call for desperate measures,' Fey notes, prompting a cameo from SNL regular Marcello Hernández who dropped in as his recurring character Domingo.

White then hit him over the head with a frying pan and declared, 'No cast members allowed.'

The sketch was tied together as Black performed a rendition of The White Stripes' famous rock hit Seven Nation Army. 

'I'm gonna fix it by singing the world's most rockin' song,' he sings as he vows to revive the dying Five-Timers Club spoof.

White came back out playing guitar and White called upon wizard background dancers, who emerged with dramatic fog.

He broke from the song to exclaim, 'I can't believe this is really happening. I think I'm in heaven. Am I in heaven?'

'We've got a great show tonight! Jack Black is here,' he said before passing the microphone to the musician, who played along and said, 'Jack White is here.'

'Stick around and we'll be White Black,' the host teased while mashing up their names before a commercial break.
