Ana Gasteyer Reveals Humbling Prank Will Ferrell Pulled On Diddy During 'SNL' Rehearsal

"It's the greatest thing that's ever happened," said Gasteyer on the "Las Culturistas" podcast.

Will Ferrell apparently couldn’t help himself from playing a humbling prank on Sean “Diddy” Combs.

The beloved funnyman was purportedly so annoyed that Combs demanded a closed set on “Saturday Night Live” to rehearse for his 1998 performance of “Come With Me” that he not only crashed it, but did so in character — as a former “SNL” crew member named Ron.

His former colleague Ana Gasteyer, whose tenure from 1996 to 2002 overlapped with Ferrell’s, recalled Wednesday on the “Las Culturistas” podcast co-hosted by current “SNL” star Bowen Yang that Combs had “shut down the whole building.”

“You can tell like the five assholes in the six years that I was there when they would be like, ‘So and so is in the building, everybody stay in your dressing rooms!’” she added. “Which is applicable if you’re a presidential candidate. But apart from that, really, it’s my house.”

Ferrell, who was dressed as Ron that day as part of an ongoing bit to amuse his colleagues, was naturally more than willing to go big and, as Gasteyer explained on the podcast, jumped at the chance when “they were like, ’Wouldn’t it be so funny if Ron just went in?’”
